Question

Please help !!!!!!!!

Answer 1

answer: 4u - 15

work: 20[(1/5)U- (3/4)]

= (
`(20)/(5)` )U - (
`(20 x 3)/(4)`)

= (4)U - (5 x 3)

= 4u - 15

Answer 2

4u-15

So, you multiply 20×1/5u giving you 4u. Then you would to the same but with -3/4 giving you -15. You can't go any farther because they don't have the same variables. So your answer is 4u-15
