Solving Equations Step by Step

What is the next step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

-3x - 4 = -x - 34

-3x - 4 + x = -x - 34 + x

-2x - 4 = -34

-2x - 4 + 4 = -34 + 4

• 2x = -30

• -2x = 38

• -2x = -30

• -2x = -38

What is the first step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

• 3x - 4 = -x - 34

• -3x + 4 = x + 34

• -3x - 4 = -x - 34

• 7x - 10 = -15x - 12

• -7x - 4 = 15x - 34

What is the next step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

-3x - 4 = -x - 34

• -3x - 4 + x = -x - 34 + x

• -3x - 4 - x = -x - 34 - x

• -3x - 4 - 34 = -x - 34 - 34

• -3x - 4 - 3x = -x - 34 - 3x

• -3x + 4 - 4 = -x - 34 - 4

What is the next step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

-3x - 4 = -x - 34

-3x - 4 + x = -x - 34 + x

• 2x - 4 = 34

• -2x - 4 = -34

• -4x - 4 = -34

• 4x + 4 = 34

• m=3

• m=-4

• m=-1

What is the next step in solving:

2x + 3 - 5x - 7 = -8x -11 + 7x -23

-3x - 4 = -x - 34

-3x - 4 + x = -x - 34 + x

-2x - 4 = -34

-2x - 4 + 4 = -34 + 4

-2x = -30

Divided both sides by -2.

• x = 1

• x = -28

• x = -15

• x = 15
