Question

5(u-1)=3u+9-2(-3-2) solve for u

Answer 1

`5(u - 1) = 3u + 9 - 2( - 3 - 2)`
Distribute 5 through the parenthesis and calculate the sum or difference from (- 3-2).


`5u - 5 = 3u + 9 - 2 * ( - 5)`
Multiply the numbers - 2 × (-5). Multiplying two negatives equals a positive (-) × (-) = (+)

=> 5u - 5 = 3u + 9 + 10
Add the numbers 9 + 10

=> 5u - 5 = 3u + 19
Move terms. Move variable 3u to the left side and change its sign. Move constant - 5 to the right side and change its sign.

=> 5u - 3u = 19 + 5
Collect the like terms and add the numbers.

=> 2u = 24
Divide both sides of the equation by 2

=> u = 12
