Answer:
x= -7
y= 3
Explanation:
6x+y= -39 -------(1)
3x+2y= -15 -------(2)
First, you start by choosing th one you want to eliminate(either x or y), but I chose to eliminate y. But there is a problem(the coefficients of the values of y are not the same). so we multiply the coefficients of y in (1) by the equation (2) and vice versa.
[6x+y= -39] ×2
[3x+2y= -15] ×1
12x+2y= -78 -----(3)
3x+2y= -15 -------(4)
Subtract 4 from 3
9x= -63
Divide both sides by 9
x= -7
Substitute the value of x in (1) or (2)
From (1),
6x+y= -39
6(-7)+ y= -39
-42+y= -39
y= -39+42
y=3
