Answer:
Equation 1: 3x+2y=5
Equation 2:2x-3y=7
We are supposed to solve the system of equations using substitution method
Take out the value of y from equation 1:
3x+2y=5
y=\frac{5-3x}{2} ---A
Substitute the value of y in 2
2x-3(\frac{5-3x}{2})=7
2x-7.5+4.5x=7
6.5x=14.5
x=\frac{14.5}{6.5}
x=2.23
Substitute the value of x in A
y = \frac{5-3(2.23)}{2}
y=-0.845
Hence The solution is (2.23,-0.845)
