Question

Solve: 2x + 15 = 43 - 5x

Answer 1

x = 4

Explanation:

Step 1: Simplify both sides of the equation

2x +15 = 43 - 5x

2x +15 = 43 + - 5x

2x +15 = - 5x + 43

Step 2: Add 5x to both sides

2x + 15 + 5x= - 5x + 43 + 5x

7x +15 = 43

Step 3: Subtract 15 from both sides.

7x +15 -15 = 43 - 15

7x = 28

Step 4: Divide both sides by 7.

7x/7 = 28/7

Therefore the X = 4

Answer 2

x = 4

Explanation:

2x + 15 = 43 - 5x

2x + 5x = 43 - 15

7x = 28

x = 28/7

x = 4
