Question

solve the following system of equations graphically 3/2x-5/4y=6,6x-5y=20

Answer 1

A=3x÷2-5y÷4=6 & B=6x-5y=20
:.
convert into x/x-intercept+ y/y-intercept=1
divide by 6
A=3x/12-5y/24=1
x/4-y/4.2=1

& divide by 20 in
B=6x-5y=20
:. 6x/20-5y/20=1
:.x/3.3-y/4=1
now u get A(4,-4.2)&B(3.3,-4)

:. show this on graph line
