Answer:
x=−8
Explanation:
Let's solve your equation step-by-step.
x2+15=x8+12
Step 1: Simplify both sides of the equation.
12x+15=18x+12
Step 2: Subtract 1/8x from both sides.
12x+15−18x=18x+12−18x
38x+15=12
Step 3: Subtract 15 from both sides.
38x+15−15=12−15
38x=−3
Step 4: Multiply both sides by 8/3.
(83)*(38x)=(83)*(−3)
x=−8
Answer:
x=−8
