Question

solve the simultaneous equations
2x + 4y = 1
3x - 5y = 7

Answer 1

Step-by-step explanation:

2x+4y=1 equation1

3x - 5y=7 equation 2

eq 1 multiply 5 and eq 2 multiply 4

eq 1 and 2 adding we get

10x+20y=5

12x-20y=28

22x=33

x=33/22

x=3/2

put value of x in equation 1

3+4y=1

y=-2/4

y=-1/2
