You will distribute the parentheses. So, it'll look like... 2.5t-5-6=9 Next step you will either add or subtract the like terms. It'll look like...... 2.5t-11=9 Next step you will add 11 to both sides.. Equation will now look like.... 2.5t=20 Then you divide 2.5t on both sides. Like this.. 2.5t/2.5 and 20/2.5 And the answer is 8.. Did that help any?
