If possible could someone show me ( with steps?) how to do this problem?

 

"Solve for y: -4y + x - 3 = 3y - 3x Use no spaces in your answer."

-4y + x - 3 = 3y - 3x      add 4y to both sides

 

x - 3  = 7y - 3x             add 3x to both sides

 

4x - 3  = 7y                   divide both sides by 7

 

(4/7) x   - (3/7)   =   y        or, written a little differently........

 

[ 4x  - 3 ] /  7   =   y

solve 4x-7y-3 = 0  This is called "Linear Diophantine Equation". It has an infinite number of solution in whole integers. Such as x=6, y=3 or x=13, y=7..........etc.

Solve for y:
-3+x-4 y = 3 y-3 x

Subtract -3+x+3 y from both sides:
-7 y = 3-4 x

Divide both sides by -7:
Answer: | y = (4x)/7-3/7

-4y + x - 3 = 3y - 3x      add 4y to both sides

 

x - 3  = 7y - 3x             add 3x to both sides

 

4x - 3  = 7y                   divide both sides by 7

 

(4/7) x   - (3/7)   =   y        or, written a little differently........

 

[ 4x  - 3 ] /  7   =   y
