Solve: 3(x+1) = 2(x-8) + 3 First, remove the parentheses by distributing (multiplying out the numbers): 3x + 3 = 2x - 16 + 3 Then, combine any like terms on the same side of the equals sign; 3x + 3 = 2x -13 Then, move the like terms on opposite sides of the equals sign to the same side of the equals sign (don't forget to change the signs). 3x -2x = -13 - 3 Then combine the like terms on the same side of the equals sign again. x = -16
The last step is always to check the answer to make sure the it is correct. So, start with the original equation, but substitute in the value for x that we just found: 3(x+1) = 2(x-8) + 3 3(-16+1) = 2(-16-8) + 3 3(-15) = 2(-24) + 3 -45 = -45 So the answer is correct!
