How do I do number 9? And can you please show work on paper

Just take it slow and easy, one small step at a time:
Write the problem : 4x + 2 = 7x - 8
Add 8 to each side: 4x + 10 = 7x
Subtract 4x from each side: 10 = 3x
Divide each side by 3 : 10/3 = x
That wasn't so bad, was it ?

4 x + 2 = 7 x − 8 4 x + 2 − 7 x − 2 = 7 x − 8 − 7 x − 2 − 3 x = − 10 / : ( − 3 ) x = 3 10 ​ x = 3 3 1 ​

To solve the equation step by step, start by isolating the variable on one side, combine like terms, and finally solve for the variable. For example, if the problem is 4 x + 2 = 7 x − 8 , you would rearrange and simplify to find x = 3 10 ​ . Always check your solution by substituting it back into the original equation.
