Answer:

y = 2 , x = -1

Step-by-step explanation:

Given = x+2y-3=0

then, x=3-2y. (1)

and given = 3x-2y+7=0

then,x=(2y-7)/3. (2)

so equating equation (1) and equation (2)

(2y-7)/3 = x=3-2y

by cross multiplication

9-6y = 2y-7

9+7 = 2y + 6y

16=8y

y = 2

if y = 2,then from equation (1)

x = 3-2y

x = 3-(2*2)

x = 3-4

x = -1

HERE IS YOUR ANSWER

HOPE ITS HELPFUL
