Answer:

0 = 0

Step-by-step explanation:

2+5x−7=3x−9+2x

Step 1: Simplify both sides of the equation.

−2+5x−7=3x−9+2x

−2+5x+−7=3x+−9+2x

(5x)+(−2+−7)=(3x+2x)+(−9)(Combine Like Terms)

5x+−9=5x+−9

5x−9=5x−9

Step 2: Subtract 5x from both sides.

5x−9−5x=5x−9−5x

−9=−9

Step 3: Add 9 to both sides.

−9+9=−9+9

0=0

I need to solve for 3x+7=-x-1

Andrew [12]

3x+7=-x-1

move -x to the other side

sign changes from -x to +x

3x+x+7=-x+x-1

3x+x+7=-1

4x+7=-1

move 7 to the other side

sign changes from +7 to -7

4x+7-7=-1-7

4x=-8

Divide by 4 for both sides

4x/4=-8/4
