Answer:

y = 8 and x = -6

Step-by-step explanation:

5x + 6y = 18 ------------ (1)

2x - 3y = 12 ------------- (2)

we have to cut out the x to find value of y

so, multiply equation (1) by 2 and equation (2) by 5

then we get,

10x + 12y = 36 ---------- (3)

10x - 15y = 60 ---------- (4)

substract equation (4) from (3)

we get,

-3y = -24

so,

= 3y = 24

= y = 24/3

y = 8

put value of y in equation (1)

5x × 6 (8) = 18

= 5x × 48 = 18

= 5x = 18 - 48

= 5x = -30

= x = -30/5

x = -6
