Subtract 3 from both sides: To isolate x, we need to get x by itself on one side of the equation. We can do this by subtracting 3 from both sides of the equation.−7−3=x+3−3
Simplify the equation: After subtracting 3 from both sides, we simplify the equation.−10=x
Isolate and find x: We have isolated x and found its value.x=−10
