Y coordinate on solving both equations comes out to be 0
-2x+3y=-6
3y = -6+2x
put the value of 3y in equation 2nd
5x-2(-6+2x) =15
5x+12-4x = 15
x=3
put value of X in 3y = -6+2x
3y = -6+2*3 = -6+6 = 0
thus y = 0

Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) $\frac{3x+4}{2}$ = 9.5

3x+4 = 9.5(2)

3x = 19-4

x = 15/3

x = 5

b) $\frac{7+2x}{3}$ = 5

7+2x = 5(3)

2x = 15-7

x = 8/2

x=4
