Answer
Success!
y = 50 and n = 100
↓Steps Explained:↓
Use the substitution method to solve:
y + n = 150
Check Format
Equation 2 is in the correct format.
Rearrange Equation 2 to solve for y:
y + n = 150
Plug Revised Equation 2 value into y:
3(y) + n = 250
3 * (150 - n) + n = 250
450 - 3n + n = 250
Group like terms:
-3n + n = 250 - 450
-2n = -200
Divide each side by -2
| -2n | |
| -2 |
| = |
| -200 |
| -2 |
| n = | -200 |
| -2 |
n = 100
Plug this answer into Equation 1
3y + 1(100) = 250
3y + 100 = 250
3y = 250 - 100
3y = 150
Divide each side by 3
| 3y | |
| 3 |
| = |
| 150 |
| 3 |
| y = | 150 |
| 3 |
y = 50
