Answer:
x + (2x-12) = 84
x = 32
Step-by-step explanation:
you can say (part 1) + (part 2) = 84
one part is x (a variable) and
other part is 12 less than twice the other: when it says "12 less" is " - 12" and twice of part one 2x, you can say (2x - 12)
(part 1) + (part 2) = 84
x + (2x-12) = 84
3x - 12 = 84
3x = 96
x = 32
(part 1) + (part 2) = 84
(32) + (2*32 - 12) = 84
(32) + (52) = 84
