Question

what is x=2+y and 3x-7y=10

Answer 1

Here

Solve x=2+y and 3x−7y=10
Steps:
I will try to solve your system of equations.
x=y+2;3x−7y=10
Step: Solve x=y+2 for x:
Step: Substitute (y+2) for x in 3x−7y=10:
3x−7y=10
3(y+2)−7y=10
−4y+6=10(Simplify both sides of the equation)
−4y+6+−6=10+−6(Add -6 to both sides)
−4y=4
−4y
−4
=
4
−4
(Divide both sides by -4)
y=−1
Step: Substitute (−1) for y in x=y+2:
x=y+2
x=−1+2
x=1(Simplify both sides of the equation)
Answer:
x=1 and y=−1
