Answer:
7y-4x.
Step-by-step explanation:
I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.
-3(2x- y) + 2y + 2(x+y)
= -6x+3y + 2y+2x+2y
= -6x+2x+3y+2y+2y
= -4x+7y.
Answer:
6x=54
Step-by-step explanation:
3x - {7-x} =29
open bracket
3x - 7 +x =29
collect like terms and equate
4x =29 +7
4x = 36
divide both sides by 4
x = 9
.
. . 6x= 6 × 9 = 54
6x= 54
