What Is The First Step Needed To Solve X-3 =-18? O Add 3 To Both Sides O Subtract 18 From Both Sides

Answers

Answer 1

Answer:

Add 3 to both sides

Answer 2

Answer with step-by-step explanation:

Add 3 to both sides

When solving equations like this, you need to make both sides as simplified as possible. In this case, x - 3 = 18, so you'd simplify the equation by adding 3 to both sides. In the end, x = 21

5/6 divide by 1/2 in simplest form

Answers

Answer:

1 2/3

Step-by-step explanation:

To divide fractions you do the Keep Change Flip tactic, meaning keep the first fraction change the operation to multiplication and reverse the second fraction.

So with that being said, 5/6*2/1 would be the equation you need to solve. This would give you 10/6 and you have to change that into a mixed number, 1 4/6 and you can reduce that to SIMPLEST FORM by dividing by 2. 4/2=2 and 6/2=3 so in the end you get 1 2/3.

Solve the following system for all solutions:

(x - 1)^2 + (y + 3)^2 = 13

x + y = -3​

Answers

Answer:

( -4, -1 ) and ( -9, - 6)

Step-by-step explanation:

Given(x - 1)^2 + (y + 3)^2 = 13 x + y = -3​Solution

From the second equation we get

x = - y - 3

Substituting x in the first equation

(- y - 3 - 1)^2 + (y + 3)^2 = 13(-y - 4)^2 + (y + 3)^2 = 13(y+4)^2 + (y+3)^2 = 13y^2 + 8y + 16 + y^2 + 6y + 9 = 132y^2 + 14y + 12 = 0y^2 +7y +6 = 0(y+1)(y+6) = 0y = - 1y = - 6

Then

x = -4x = - 9

Solve for x.
10x + 44
8x - 23

Answers

Answer:

Simplifying

10x + 44 = 8X + -23

Reorder the terms:

44 + 10x = 8X + -23

Reorder the terms:

44 + 10x = -23 + 8X

Solving

44 + 10x = -23 + 8X

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-44' to each side of the equation.

44 + -44 + 10x = -23 + -44 + 8X

Combine like terms: 44 + -44 = 0

0 + 10x = -23 + -44 + 8X

10x = -23 + -44 + 8X

Combine like terms: -23 + -44 = -67

10x = -67 + 8X

Divide each side by '10'.

x = -6.7 + 0.8X

Simplifying

x = -6.7 + 0.8XStep-by-step explanation:

========================================================

Explanation:

Any point is of the form (x,y). The x coordinate is always listed first.

We're given (2, ___) where the y value is missing in the blank.

So we're given x = 2.

Plug this into the given equation to find y

y = 2x+5

y = 2*2+5 ... replace x with 2

y = 4+5

y = 9

Therefore (2, ___) updates to (2, 9 )
