Let's find x on each of the following equations.
Equation 1: 2 + x = 9
[tex]\begin{gathered} \text{ 2 + x = 9} \\ \text{ 2 + x - 2 = 9 - 2} \\ \text{ x = 7} \end{gathered}[/tex]
Therefore, the answer is 7.
Equation 2: 3x - 2 = 25
[tex]\begin{gathered} \text{ 3x - 2 = 25} \\ \text{ 3x - 2 + 2 = 25 + 2} \\ \text{ 3x = 27} \\ \text{ }\frac{\text{3x}}{\text{ 3}}\text{ = }\frac{\text{ 27}}{\text{ 3}} \\ \text{ x = 9} \end{gathered}[/tex]
Therefore, the answer is 9.
