Answer:
x+y=12
Step-by-step explanation:
First, substitute 3y for the spots with x:
2(3y) + 2y = 24
6y+ 2y = 24
8y= 24
y= 3
Then sub in 3 in the y place:
x= 3(3)
x= 9
Then plug in the x and y values in the equation:
9 + 3 =12

Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A

Answer:
y = 2/3x - 2
Step-by-step explanation:
y-intercept:
Point line crosses the y axis is -2 which is point (0, -2).
slope:
points (-3, -4) and (3, 0)
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-4)) / (3 - (-3))
= 4 / 6
= 2/3
Equation of line using your y-intercept and slope from above:
y = mx + b
y = 2/3x - 2
