Use substitution to solve the linear system of equations. y=4x3x+5y=-46(-8, -2)(8, -2)(-2, 8)(-2, -8)

(- 2, - 8 )

Step-by-step explanation:

given the 2 equations

y = 4x → (1)

3x + 5y = - 46 → (2)

Substitute y = 4x into (2)

3x + 5(4x) = - 46

3x + 20x = - 46

23x = - 46 ( divide both sides by 23 )

x = - 2

substitute x = - 2 into (1)

y = 4 × - 2 = - 8

solution (- 2, - 8 )
