Use substitution to solve the linear system of equations.

goblinko [34]

Answer:

(4, - 2 )

Step-by-step explanation:

Given the 2 equations

x = 4 → (1)

- y = $\frac{1}{2}$ x → (2)

Substitute x = 4 into (2)

- y = $\frac{1}{2}$ × 4 = 2 ( multiply both sides by - 1 )

y = - 2

Solution = (4, - 2 )
