Step-by-step explanation:
Remark. The easiest way to solve this is to make the coefficients of one of the letters = to the same coefficient in the other equation
Set up and solve
x + y = 24
3x + 5y = 100 Multiply the first equation by 3
<u>3x + 3y = 72 </u> Subtract
2y = 28 Divide by 2
y = 28/2
y = 14 <<<<<< Answer for y
Step 2
Solve for x
x + y = 24
x + 14 = 24 Subtract 14 from both sides.
x = 24 - 14
x = 10 <<<<Answer for x
Check to see if it works.
3x + 5y = 100
3*10 + 5*14 = 100
30 + 70 = 100 Checks.
