Question

solve by using substitution method x÷3+Y÷2=3
and x-2y=2​

Answer 1

Answer:

♦ By substitution method :

⭐ x + 2y = -1

=> x = -1 - 2y -----------(1)

also, we have

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

Putting value of x in equation (2) we get,

=> 2( -1 - 2y) - 3y = 12

=> -2 - 4y - 3y = 12

=> -7y = 12 + 2

=> -7y = 14

=> y = -2 -----------(3)

putting value of y in equation (1) we get,

=> x = -1 - 2y

=> x = -1 - 2 × -2

=> x = -1 +4

=> x = 3

Hence, x = 3 and y = -2
