Steps:
(x-2)=4x
Pretend that there is a one in front of x-2
1(x-2)=4x
Multiply the bracket by 1
x-2=4x
Move x to the other side .Whenever you move a number or letter the sign changes.
x-x-2=4x-x
-2=3x
Divide by 3 for -2 and 3
-2/3=3/3 x
x=-2/3
Check answer by using substitution method
(-2/3-2)=4(-2/3)
(-2/3-6/3)=-8/3
-8/3=-8/3
Answer is -2/3
