Answer:
Solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 we get x=2 and y=-3
Solution set = {2,-3}
Step-by-step explanation:
We need to solve this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7
let:

Finding value of x from equation 2 and putting in eq(1)

Putting value of x in eq(1)

So, we get y=-3
Now put value of y in equation 2 to find value of x

So, we get value of x =2
So, solving this simultaneous equation by using substitution method 3x-2y=12 and x+3y=-7 we get x=2 and y=-3
Solution set = {2,-3}
( yx + 4x - 5 )( y + 1 )
