Question

Solve the equation. 2|7-7x| = 2x+4
A. x=3/2 x=5/6
B. x=3/2 x=5/8
C. x= 5/8
D. x=3/2

Answer 1

Can you divide both side by 2:
2|7-7x| = 2x+4

Answer 2

mod(7-7x)=x+2

Answer 3

when 7-7x=0
x=1

Answer 4

|7-7x|=2x+4
7-7x = 2x+4 or 7-7x= -(2x+4)
solve these equation

Answer 5

but u need to check the answers also...because 1st equation is for x less than one...and 2nd one is for x greater than one.

Answer 6

mod(7-7x)= 7-7x, when x is less than 1.
mod(7-7x)=-(7-7x), when x is greater than one.
