2x-3y+1
-4
16x-9y
15x-2
Step-by-step explanation:
I put parenthesis in each equation to help you see where to solve the equation first.
(x+2x)+4y
3x+4y
5y+6+2x-3(the 6 and -3 are apart, but you need to do that first)
2x+5y+3
3x-4x+7x(i did not need to put parenthesis here because they are all like terms)
-1+7x
6x
(-2x-x)+(7y-5y)
2y-3x
(-4x+9x)-8+x
5x-8+x
6x-8
(-2x-x)+(7-10)
-3x-3
(-4-5)+(7x+6x)
13x-9
5x-4x-2x+x(i did not need to put parenthesis here because they are all like terms)
x-1x
0
2x+(4y-7y)+1
2x-3y+1
4-3-5(I can not put parenthesis here because if i do it will look like you are supposed to multiply when you are not)
1-5
-4
14x+2x(-5y-4y)
16x-9y
(10x+5x)(-4+2)
15x-2
