Exercise 31 Page 85

To solve the equation we need to isolate t on one side of the equation. By dividing both sides by 2.2, we can cancel it from the right-hand side.

11=2.2t

DivEqn

.LHS /2.2.=.RHS /2.2.

11/2.2=2.2t/2.2

Rearrange equation

t=5

Therefore, t=5 is the solution to the equation. To check that we have the correct solution, we can substitute t=5 into the original equation and simplify.

11=2.2t

Substitute

t= 5

11? =2.2 * 5

Multiply

11=11

Since the left-hand side and right-hand side are equal, t=5 is the correct solution.
