Question

×+4y=16 -×+5y=11

Answer 1

Are you told to solve these for the variables x and y?

Answer 2

x+4y=16
-x+5y=11

Since 4y does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 4y from both sides.
x=-4y+16
-x+5y=11

Since the equation was solved for x, replace all occurrences of x in the other equations with the solution (-4y+16).
x=-4y+16
-(-4y+16)+5y=11

Multiply -1 by each term inside the parentheses.
x=-4y+16
(4y-16)+5y=11

Since 4y and 5y are like terms, add 5y to 4y to get 9y.
x=-4y+16
9y-16=11

Move all terms not containing y to the right-hand side of the equation.
x=-4y+16
9y=27

Since the equation was solved for y, replace all occurrences of y in the other equations with the solution (3).
x=-4y+16
y=3

Since the equation was solved for y, replace all occurrences of y in the other equations with the solution (3).
x=-4(3)+16
y=3

Multiply -4 by each term inside the parentheses.
x=-12+16
y=3

Add 16 to -12 to get 4.
x=4
y=3

This is the solution to the system of equations.
x=4
y=3

(4, 3)

Hope this helps. :)
