Question

10. (a) What should be subtracted from 2x' + x - 10 to get 2x - 7x + 22 ?
(b) What should be subtracted from 2x + 11x + 22 to get x'- 19x + 2x - 2?
(c) What should be subtracted from y' - 3y + 3y +6 to get y - 4y + 5y + y + 5?

Answer 1

Answer:

do by algebra simpley takr the number as a which u have to find then do what operation u want

Answer 2

Step-by-step explanation:

a) Let y be subtracted from 2x' + x - 10 to get 2x - 7x + 22

Therefore,

2x' + x - 10 - y = 2x - 7x + 22

8x - y = 32

Therefore ,

y = 8x - 32 must be subtracted

b) Let y be subtracted from 2x' + 11x + 22 to get x-19x+2x-2

Therefore,

2x' + 11x +22 - y = x-19x + 2x -2

29x - y = -24

Therefore ,

y = 29x +24 must be subtracted
