Question

Simplify.
10x - 3y + 2x - 4y

Answer 1

x and y are our variables, so we can "pair" them up, so to speak.

10x +2x= 12x
-3y -4y= -7y

12x -7y

Answer 2

Evaluate and simplify if possible:
3(x - 2y) - 4(2x + 3y)

for x = -1 and y = 3

Answer 3

ok any time soon

Answer 4

3( -1 -2(3)) - 4)(2(-1)+3(3))
3(-1 -6) -4 ( -2 +9)
3( -7) - 4(7)
-21 - 28
-49

Answer 5

\[10x-3y+4y-2x\]
