x = 10
Step-by-step explanation:
First, to solve for x, you need to isolate the variable, meaning that it needs to be the only term on one side of the equation. To do this, we'll just cancel out the -3 by adding +3 on both sides of our equation.
x - 3 = 7
+3 +3
x = 10
Leaving us with our answer, x = 10
Hope this helped :)

x=−3 or x=5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2−15=2x
Step 1: Subtract 2x from both sides.
x2−15−2x=2x−2x
x2−2x−15=0
Step 2: Factor left side of equation.
(x+3)(x−5)=0
Step 3: Set factors equal to 0.
x+3=0 or x−5=0
x=−3 or x=5
