x=-5/6y+6x=56y+6

Explanation:

Given:" "y=-5/6 x+5 y=56x+5

Subtract color(red)(5)5 from both sides

color(green)(ycolor(red)(-5)=-5/6x+5color(red)(-5))y5=56x+55

y-5=-5/6xy5=56x

Multiply both side by -11 to make -5/6x56x positive

-y+5=+5/6xy+5=+56x

Multiply both sides by 6/565. Turns the 5/656 from 5/6x56x into 1

6/5(-y+5)=x65(y+5)=x

-5/6y+6=x56y+6=x

Write as: x=-5/6y+6x=56y+6

x=-6/5y+6x=65y+6

Explanation:

y=-5/6x+5y=56x+5

:.-5/6x+5=y

multiply both sides by-6/5

:.-5/6x xx (-6/5)+5/1 xx (-6/5)=y xx -6/5

:.x-6=(-6)/5y

:.x=(-6)/5y+6
