Simplify each expression

Answer 1

For (-0.75+6)-(2.5x-9) all you have to do is multiply the negative into the 2nd brackets and collect like terms. Same with 8(5x-3y) all u have to do is multiply in the 8.

for the 4x+20 and 6x+54 all u do is factor out a common number(LCD- lowest common denominator)
