Simplify. 1/4(3x−7)+3/4x
Setler [38]

Answer:

6/4x + -7/4 also know as 1 2/4x - 1 3/4 which simplified even further is

1 1/2x - 1 3/4

Use the distributive property to multiply  1/4  by 3x−7.

Multiply 1/4 and 3 to get 3/4

Multiply 1/4  and −7 to get  -7/4

Combine 3/4x and 3/4x to get 6/4x or 3/2x.
