Answer:
[tex]\Large\boxed{1)~6x+7}[/tex]
[tex]\Large\boxed{2)~-7x+5y+8}[/tex]
Step-by-step explanation:
Given expression
4x + 7 + 2x
Move like terms together
= 4x + 2x + 7
= (4x + 2x) + 7
Combine like terms
[tex]\Large\boxed{=6x+7}[/tex]
Given expression
-4x + 3y - 3x + 8 + 2y
Move like terms together
= -4x - 3x + 3y + 2y + 8
= (-4x - 3x) + (3y + 2y) + 8
Combine like terms
[tex]\Large\boxed{=-7x+5y+8}[/tex]
Hope this helps!! :)
