Start with the equation:
11 = −7(−5u + 19) − 17u
Distribute −7:
11 = 35u − 133 − 17u
Combine like terms:
11 = 18u − 133
Add 133 to both sides:
144 = 18u
Divide by 18:
u = 8
(Check: −7(−5·8+19)−17·8 = −7(−40+19)−136 = −7(−21)−136 = 147−136 = 11)
11 = −7(−5u + 19) − 17u
Distribute −7:
11 = 35u − 133 − 17u
Combine like terms:
11 = 18u − 133
Add 133 to both sides:
144 = 18u
Divide by 18:
u = 8
(Check: −7(−5·8+19)−17·8 = −7(−40+19)−136 = −7(−21)−136 = 147−136 = 11)
