Solutions of Equations When you take an equation and replace the variables with numbers, you can make the statement either or. If it becomes true, then the number is called a of the equation.

IS IT A SOLUTION? Equation: Is the number 1 a solution to the equation? Is the number 2 a solution to the equation? Is the number 3 a solution to the equation?

Find the solution set for 4 a + 7 = 23 if the replacement set is {2, 3, 4, 5, 6}.

Find the solution set for 6 c – 5 = 7 if the replacement set is {0, 1, 2, 3, 4}. A. {0} B. {2} C. {1} D. {4}

SOLVING AN EQUATION This means you found of an equation. x+2=5 Ask yourself the question, “What number can be added to 2 to obtain 5? ”

Solve 3 + 4(23 – 2) = b.

Solve (42 – 6) + f – 9 = 12.

Solve 4 + (32 + 7) ÷ n = 8.

Solve 4 n – (12 + 2) = n(6 – 2) – 9.

Solve 2 n + 72 – 29 = (23 – 3 • 2)n + 29.

Solve (5 + 8 ÷ 4) + 3 k = 3(k + 32) – 89.
