If 5x+3y=41 and x+y=11, then the value y-x is

Step-by-step explanation:

Subtract  y  from both sides of the equation.

Replace all occurrences of x  in  with  11 -y

simplify

add -5y and 3y

Solve for  y  in the second equation.

Move all terms not containing  y  to the right side of the equation.

Divide each term by  − 2  and simplify.

Replace all occurrences of  y  in  x

simplify.

Replace the variable  x  with  4  in the expression.

Replace the variable  y  with  7  in the expression.

Multiply  − 1  by  4 .

Subtract  4  from  7 .
