Answer:
x = 4
Step-by-step 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
