How do you solve this?

Question

100-4u/3 =5u+6/4 + 6?

Answer 1

Include brackets please.

(100-4u)/3 = [(5u+6)/4] + 6

Multiply all terms by 12 (LCD) to get

4(100-4u) = [3(5u+6)] + 6(12)

400-16u = 15u+18+72

400 - 16u = 15u + 90

400 - 90 = 15u + 16u

310 = 21u

u = ~14.76

Answer 2

i got 982/55

cross multiply 10(100-4u) = 3(5u+6)

1000-40u = 15u+18

add the 40 giving youu 1000=55u+18

subtract 18 = 982 = 55u

givng you u= 982/55

i plugged it in and i got the same answer for both, hopes this help :)
