I might be wrong but I think the answer would be -x+2x+6 as a simplified version because if you use the equation (x+4•x+3)-3x(x+1)=a (or any letter you choose), you will get 3x+x^2+12+4x-3x-3x^2=y. Then, you can combine like terms:
4x-2x+12=a

Three ordered pairs that solve the equation x - 4 Y equals -18
lawyer [7]
X-4y=-18
an easy way is to solve for oone variable
solve for x
add 4y both sides
x=4y-18

when y=1, x=-16
when y=0, x=-18
when y=2, x=-10

(x,y)
so some orderd pairs are
(-16,1)
(-18,0)
(-10,2)
