Step Work Justification
1 2(x + 1) = 10 Given
2 2x + 2 = 10 Distributive Property
3
4 2x = 8 Simplify
5 two times x over two equals eight over two Division Property of Equality
6 x = 4 Simplify
A. 2x + 2 + 2 = 10 + 2; Addition Property of Equality
B. 2x + 2 − 2 = 10 − 2; Subtraction Property of Equality
C. (2x + 2)(2) = 10(2); Multiplication Property of Equality
D. the quantity two times x plus two all over two equals ten over two; Division Property of Equality
