Simplify: 4(2a - 3) + 5

Explanation:
This tests distributing a factor across the terms and then combining like terms. Distribute the 4: 4 times 2a is 8a, and 4 times -3 is -12. Then bring down the +5 and combine the constants: -12 + 5 equals -7. So the simplified expression is 8a - 7. This is as simple as it gets because you can’t combine the variable term with the constant.
