Question

solve these simultaneous equations
5x - 2y=13
2x-3y=3

Answer 1

Answer:

5x-2y=13-------(1)

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

multiply (1) by 2 and (2) by 5

we get,

10x-4y=26------(3),and

10x-15y=15------(4)

subtracting (3) and (4)

we get,

y= 1

Now putting the value of y in (1)

5x-2(1)=13

5x = 13 +2

5x=15

x=15/5

x=3
