Solve 3a a = 90 4a + 6 = 90 – 6 4a = 84 a = Combining Like Terms:
Using the Distributive Property To solve algebra equations using the distributive property, we need to distribute (or multiply) the number to each term in the expression.
Solve 3(2x + 5) = 3 6x + 15 = x = –12 6 x = –2
Examples: 1) 2) 2(x – 3) = 8 2x – 6 = x =14 x = 7 2 2
Examples: 3) 4)
