Step-by-step explanation:
-x+2y=-6
x-2y=6
x=2y+6
substitute in 2x-3y=11 gives us 2(2y+6)-3y=11
4y+12-3y=11
y=-1
-x+2(-1)=-6
-x=-4
x=4
Step-by-step explanation:
-2x,7x and 2x,x3
look for the same variables or look if they both have a negative or a positive without a variable , example: -2.345 has the same terms as -5.99
