Answer:
Step-by-step explanation:
<u>Given the system of equations</u>
<u>Divide 3 on both sides of the 2) equation</u>
<u>Current system</u>
<u>Substitute 1) equation into the 2) equation</u>
<u>Combine like terms</u>
<u>Subtract 15 on both sides</u>
<u>Divide 4 on both sides</u>
<u>Substitute the x value into one of the equations to find the y value</u>

Answer:
This question is impossible! For two different variables, we need two different equations. Without that, there is no hope! :)
A. (4)5 x (4)4 = 36 OR 4(5 x 4) = 36
b. No you would not. 5(5 x 4) = 45 which is out of your budget.
x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
