Write equivalent expressions for each:
a. 2x+5x+7-3
b. 4x-2y=10x
c. 2p+12+2p-8

A. 2X+5X+7-3
= (2X+5X)+ (7-3) (combine like terms)
= 7X+ 4

B. 4X-2Y+10X
= (4X+ 10X) -2Y (combine like terms)
= 14X -2Y

C. 2P+12+2P-8
= (2P+ 2P)+ (12-8) (combine like terms)
= 4P+ 4

Final
A. 7X+4
B. 14X -2Y
C. 4P+ 4

Hope this helps~

A.
2x + 5x + 7 - 3
(2+5)x + (7-3)
7x + 4

B.
4x - 2y + 10x
4x + 10x - 2y
(4+10)x - 2y
14x - 2y

C.
2p + 12 + 2p - 8
2p + 2p + 12 - 8
(2+2)p + (12-8)
4p + 4
