How do you solve 4x - 2x - 2 equals -42?
4X - 2X - 2 = - 42 preform the indicated variable subtraction ( 4X - 2X ) 2X - 2 = - 42 add 2 to each side 2X = - 40 divide both sides integers by 2 X = - 20 -------------check in original equation 4(- 20) - 2(- 20) - 2 = - 42 - 80 + 40 - 2 = - 42 - 42 = - 42 ---------------checks
