Answer:
x = 6/7, y = 33/7
Explanation:
y = 2x + 3 ----eq(1)
3x + 2y = 12 ----eq(2)
Substituting value of "y" from eq(1) into eq(2)
3x + 2(2x + 3) = 12
3x + 4x + 6 = 12
7x = 12-6
x = 6/7 ---eq(3)
Substituting value of x or eq(3) into eq (1)
y = 2(6/7) +3
y = 12/7 + 3
y= 12 + 21/7
y= 33/7
Therefore, x = 6/7 and y = 33/7
