Question

52 = 1/2x + 15 - 3.25x - 7please show step by step !! ​

Answer 1

Answer:

x = -16

Step-by-step explanation:

52= 1/2x+15−3.25x−7

Combine 1/2x and −3.25x to get −11/4 x.

52= −11/4x+15−7

Subtract 7 from 15 to get 8.

52=−11/4x+8

Swap sides so that all variable terms are on the left hand side.− 11/4x+8=52

Subtract 8 from both sides.

− 11/4x=52−8

Subtract 8 from 52 to get 44.

−11/4 x=44

Multiply both sides by − 4/11

​ the reciprocal of − 11/4

​x=44(−4/11)

​Express 44(−4/11 ) as a single fraction.

x= 44(−4)

​Multiply 44 and −4 to get −176.

x= −176/11

​Divide −176 by 11 to get −16.
