Answer:
(15,18)
Step-by-step explanation:
write two equations with the information provided.
2x + 3y = 84
x + 4y = 87
use the property of substitution to answer.
x + 4y = 87, x = 87 - 4y
2(87 - 4y) + 3y = 84
174 - 8y + 3y = 84
174 - 84 = 8y - 3y
90 = 5y
90/5 = y
y = 18
Add the value of Y to an original equation. Solve for X
2x + 3(18) = 84
2x + 54 = 84
2x = 84 - 54
2x = 30
x = 30/2
x = 15

Step-by-step explanation:
there are 10 boxes in total, slope is y = mx + b
the slope is always the constant.
constant: number without a variable.
y - intercept:
y = mx + <u>b</u>
<u>if there is nothing after the slope it means the y -intercept is 0</u>
