Question

Solve the system of equations x - 2y = 2 and

Answer 1

We solve X simultenously
x - 2y =2................equation 1
3x - 5y =9.............equation 2
find urself third equation frm dis two equations
x = 2+2y...........equation 3
SUB: 3 IN 2
3(2+2y)-5y =9
solve y
6+6y-5y=9
6y-5y=9-6
1y=3
divide both side by 1
therefore Y=3

SUB:Y=3 IN EQUATION 3
x=2+2(3)
x=8
