Answer:
Add 3y to both sides of the equation.
x=−2+3y
x+3y=16
Replace all occurrences of x with −2+3y in each equation.
−2+6y=16
x=−2+3y
Solve for y in the first equation.
y=3
x=−2+3y
Replace all occurrences of y with 3 in each equation.
x=7, y=3
The solution to the system is the complete set of ordered pairs that are valid solutions. ( 7 , 3 )
The result can be shown in multiple forms. Point Form: ( 7, 3 )
Equation Form: x=7, y=3
