Answer:
x = 2; y = 3
Step-by-step explanation:
x - y + 1 = 0 ⇒ y = x+1
3x+2y-12 = 0
⇒ 3x + 2(x+1) - 12 = 0
⇒ 3x + 2x +2 - 12 = 0
⇒ 5x = 10
⇒x = 2
y = x+1
⇒ y = 2+1
⇒ y = 3

Answer:
x = 2
y = 3
Step-by-step explanation:
Using Substitution method,
x - y + 1 = 0
x = y - 1 ------ (i)
3x + 2y - 12 = 0 ----- (ii)
3(y - 1) + 2y - 12 = 0
3y - 3+ 2y - 12 = 0
5y - 15 = 0
5y = 15
y = 3
x = y - 1
x = 3 - 1
x = 2
