Answer:
280
Step-by-step explanation:
Set up a ratio to solve.
Mr. Fraser's class has 20 soccer playing students, and 14 are boys.

x= 280
Answer:
y = -17
Step-by-step explanation:
5 + 3(y - 4) = 5(y + 2) - y Distribute
5 + 3y -12 = 5y + 10 - y Combine like terms
-7 + 3y = 4y + 10
+7 +17 Add 17 to both sides
3y = 4y + 17
-4y -4y Subtract 4y from both sides
-y = 17 Divide both sides by -1
y = -17
