Question

what is x=12+y and 4x+9y=-17

Answer 1

Here you go

Solve x=12+y and 4x+9y=−17
Steps:
I will try to solve your system of equations.
x=y+12;4x+9y=−17
Step: Solve x=y+12 for x:
Step: Substitute (y+12) for x in 4x+9y=−17:
4x+9y=−17
4(y+12)+9y=−17
13y+48=−17(Simplify both sides of the equation)
13y+48+−48=−17+−48(Add -48 to both sides)
13y=−65
13y
13
=
−65
13
(Divide both sides by 13)
y=−5
Step: Substitute (−5) for y in x=y+12:
x=y+12
x=−5+12
x=7(Simplify both sides of the equation)
Answer:
x=7 and y=−5
