step work justification
1 2(x + 1) = 10 given
2 2x + 2 = 10 distributive property
3
4 2x = 8 simplify
5two times x over two equals eight over two division property of equality
6 x = 4 simplify
2x + 2 + 2 = 10 + 2; addition property of equality
2x + 2 − 2 = 10 − 2; subtraction property of equality
(2x + 2)(2) = 10(2); multiplication property of equality
the quantity two times x plus two all over two equals ten over two; division property of equality
