Question

If x=5,solve for y.(Recall you can ue either original equation).y=x-6-2x+3y=-13

Answer 1

Using first equation

y=x-6

substitute x = 5 into the equation

y = 5-6

y = -1

Or

Using second equation

-2x+3y=-13​

substitute x = 5 into the equation

-2(5) + 3y = -13

-10 + 3y = -13

3y = -13 + 10

3y = -3

y = -3/3

y = -1
