Question

Is 2(x - 3) equals 2x plus 5 a solution

Answer 1

2(x - 3) = 2x + 5      Distribute/multiply 2 into (x - 3)

2x - 6 = 2x + 5     Add 6 on both sides

2x = 2x + 11     Subtract 2x on both sides

2x - 2x = 11

0 = 11

This is not a solution because they have to be equal to each other or the same on both sides of the equation
