Question

Simplify the following algebraic expression 3/4 (1/2x-12)+4/5

Answer 1

Explanation:

The LCD here is 120. Multiplying both terms by 120 and then dividing the result by 120 yields

90(1/2x - 12) + 96 45x - 1080 + 96 45x - 984

-------------------------- = ------------------------------- = ----------------------

120 120 120

Answer 2

y = 3/8x - 9 + 4/5

Explanation:

assuming y = 3/4 (1/2x-12)+4/5

multiply 3/4 and (1/2x - 12)

y = 3/8x - 9 + 4/5
