Answer:
4 need to join the club to remain same to grade 8th
First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:
-15.5t + 3.1t = -13.44 + 10.56 - 13.24
Now combine the numbers on both sides of the equation and solve for t:
-12.4t = -16. 12
t = 1.3
