What value(s) of x will make each equation below true? Homework Help ✎

1. $x+5=5$

2. $2x−6=3x+1−x−7$

Combine like terms on both sides of the equation.
2x − 6 = 2x − 6

2x − 6 = 2x − 6
What values of x will make this equation true?

x can equal any number. If you don't understand why, try substituting different numbers in for x.

3. $3x+1=43$

Subtract 1 from each side.

3x + 1 = 43
−1 −1
3x = 42

Divide each side by 3.

x = 14

4. $4x−1=4x+7$

Subtract 4x from both sides of the equation. If there is no variable in the final equation, what does that tell you about the final solution?
