Answer:
[tex]u=-9/7[/tex]
Step-by-step explanation:
Given equation:
[tex]5u+3-2(-6u-6)=3(u-1)[/tex]
Solving the brackets
[tex]5u+3-2(-6u)-2(-6)=3(u)-3(1)[/tex]
[tex]5u+3+12u+12=3u-3[/tex]
Taking the terms of u to one side and to find the value of u
[tex]5u+12u-3u=-3-3-12[/tex]
[tex]14u=-6-12\\14u=-18\\u=-18/14\\[/tex]
On simplifying by dividing numerator and denominator by 2
[tex]u=-9/7[/tex]
