Hello There,
Do you need help with the actual equation?
Delilah R.
-3x+5-y
Simplifying
-3x + 5 + -1y = 0
Reorder the terms:
5 + -3x + -1y = 0
Solving
5 + -3x + -1y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5' to each side of the equation.
5 + -3x + -5 + -1y = 0 + -5
Reorder the terms:
5 + -5 + -3x + -1y = 0 + -5
Combine like terms: 5 + -5 = 0
0 + -3x + -1y = 0 + -5
-3x + -1y = 0 + -5
Combine like terms: 0 + -5 = -5
-3x + -1y = -5
Add 'y' to each side of the equation.
-3x + -1y + y = -5 + y
Combine like terms: -1y + y = 0
-3x + 0 = -5 + y
-3x = -5 + y
Divide each side by '-3'.
x = 1.666666667 + -0.3333333333y
Simplifying
x = 1.666666667 + -0.3333333333y
2y=6x+10
Simplifying
2y = 6x + 10
Reorder the terms:
2y = 10 + 6x
Solving
2y = 10 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '2'.
y = 5 + 3x
Simplifying
y = 5 + 3x
Hope this helps!
Delilah R.

You need help solving SYSTEMS of EQUATIONS, but you did not submit 2 equations, but ONE (1) expression and ONE (1) equation instead. IF YOU NEED US TO HELP YOU, YOU NEED TO DO A BETTER JOB OF SUBMITTING THE CORRECT INFORMATION TO US. IT IS NOT FAIR TO OTHERS WHO DO THIS, AND TO US TO CONTINUALLY ASK THAT PEOPLE RESUBMIT PROBLEMS THAT THEY NEED HELP WITH.
PLEASE TAKE THE TIME TO CHECK YOUR WORK, AND MAKE SURE THAT YOU SUBMIT THE CORRECT INFORMATION TO US.
