If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
2x + 7 = 11 - 2x add 2x to both sides 4x + 7 = 11 subtract 7 from both sides 4x = 4 divide both sides by 4 x = 1
7 - 2x = 11 2x = 7 - 11 = -4 Therefore, x = -2
The conditional statement is: "If 2x - 5 = 11, then x = 8" The biconditional statement is the statement that contains "if and only if". Some textbooks or mathematicians use this symbol ⇔. The biconditional statement of the given is: x = 8 ⇔ 2x - 5 = 11 OR x = 8 if and only if 2x - 5 = 11.

If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
2x - 5 = 11 2x = 11 + 5 2x = 16 2x /2 = 16 /2 x = 8
2x-3 = 11 2x = 11+3 2x = 14 x = 7
2x+3 = -11 2x = -11-3 2x = -14 x = -7

2x + 7 = 11 - 2x add 2x to both sides 4x + 7 = 11 subtract 7 from both sides 4x = 4 divide both sides by 4 x = 1
