x = -22/3 = -7.333
Step by step solution :
Step 1 :Equation at the end of step 1 : x 1
(—-(—•(12-x)))-((7x+3•(8-x))-8) = 0
2 2
Step 2 : 1
Simplify —
2
Equation at the end of step 2 : x 1
(— - (— • (12 - x))) - (4x + 16) = 0
2 2
Step 3 :Equation at the end of step 3 : x (12 - x)
(— - ————————) - (4x + 16) = 0
2 2
Step 4 : x
Simplify —
2
Equation at the end of step 4 : x (12 - x)
(— - ————————) - (4x + 16) = 0

Step 5 :Adding fractions which have a common denominator :
5.1 Adding fractions which have a common denominator
Combine
the numerators together, put the sum or difference over the common
denominator then reduce to lowest terms if possible:
x - ((12-x)) 2x - 12
———————————— = ———————
2 2
Equation at the end of step 5 : (2x - 12)
————————— - (4x + 16) = 0
