X=10–5y
3(10 – 5y)+6y=12
30–15y+6y=12
30 – 9y=12
-9y=-18
y= 2
Joey has to solve the system of equations using substitution. He has completed the work shown. What should be his next step?
Nothing, he is done
He needs to write his solution as an ordered pair (0.2).
He needs to plug back into one of the equations to find x.
He needs to check his work to make sure he made no mistakes.

31÷13

do 31÷13 and u will get ur answer

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

x= 3^y
