Question

Match the reasons with the statement.

Given: 2 (x+3) = 8
To Prove: x = 1

(a) Distributive Postulate 1.) 2(x+3) = 8
(b) Subtraction property of equality 2.) 2x + 6 = 8
(c) Addition property of equality 3.) 2x = 2
(d) given 4.) x = 1

Answer 1

2(x+3)=8
2x+6=8
2x=2
x=1

(b) Subtraction property of equality  2.) 2x+6=8       2x=8-6     2x=2
