Exercise 17 Page 56

Substitute and simplify.

No.

Practice makes perfect
By substituting the given number into the equation and simplifying, we can determine whether the given number is a solution. Remember to follow the order of operations.
5b+1=16
5( - 3)+1? =16
- 15+1? =16
- 14≠ 16
Because the left-hand side and right-hand side of the equation are not equal, - 3 is not a solution.
