Question

For each ordered pair, determine whether it is a solution to the system of equations.

Answer 1

Answer:

Step-by-step explanation:

Simplifying

4x + 2y = 18

Solving

4x + 2y = 18

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

4x + 2y + -2y = 18 + -2y

Combine like terms: 2y + -2y = 0

4x + 0 = 18 + -2y

4x = 18 + -2y

Divide each side by '4'.

x = 4.5 + -0.5y

Simplifying

x = 4.5 + -0.5y

////////////

Simplifying

y = -2 + 9

Combine like terms: -2 + 9 = 7

y = 7

Solving

y = 7

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 7
