Answer:
x= 1/2
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−1)(x+7)=(x+1)(x−3)
Step 1: Simplify both sides of the equation.
x2+6x−7=x2−2x−3
Step 2: Subtract x^2 from both sides.
x2+6x−7−x2=x2−2x−3−x2
6x−7=−2x−3
Step 3: Add 2x to both sides.
6x−7+2x=−2x−3+2x
8x−7=−3
Step 4: Add 7 to both sides.
8x−7+7=−3+7
8x=4
Step 5: Divide both sides by 8.
8x/8 = 4/8
x = 1/2
