Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:(7,6)
Equation Form: x=7, y=6
2x+y=20
6x-5y=12
First get y by its self
2x+y=20
y= -2x+20
Now plug into second equation for y
6x-5(-2x+20)=12
6x+10x-100
16x-100=12
16x=112
x=7
now plug in x value into first equation and solve for y
2(7)+y=20
14+y=20
y= 6
Now check by plugging x and y values back into equation
2(7)+6=20
6(7)-5(6)=12
They both work so x=7 and y =6
