Answer 4

i know but so i just add the 3 and it' ll give me the answer?

Answer 5

too both of the sides?

Answer 6

No that's just the first step
2x-3=-9
2x-3 + 3 = -9 +3
2x =-9 + 3
2x =-6
now divide both sides by 2
2x/2 = -6/2
x = -3

Now you have to substitute the value of x (that is -3 ) in the equation x+y=-2

can you try that?
