Question

Find the solution of this system of equations.
separate the x-and y- values with a comma.
x=5+y
28x-9y=-12

Answer 1

I will try to solve your system of equations.
x=y+5;28x−9y=−12
Step: Solve x=y+5 for x:
Step: Substitute (y+5) for x in 28x−9y=−12:
28x−9y=−12
28(y+5)−9y=−12
19y+140=−12(Simplify both sides of the equation)
19y+140+−140=−12+−140(Add -140 to both sides)
19y=−152
19y19=−15219(Divide both sides by 19)
y=−8
Step: Substitute (−8) for y in x=y+5:
x=y+5
x=−8+5
x=−3(Simplify both sides of the equation)
Answer:
x=−3 and y=−8
