Solving equations is quite easy once you understand how. To solve an equation, we must isolate the variable and have the opposite side be simplified. We can do this by changing both sides.

4x-9=23
   +9  +9
4x=32
/4   /4
x=8

With the math above, you can see that the solution to this equation is x=8.

Hello Friend!

Solution for 4x-9=23 equation:
Simplifying:
[tex]4x + -9 = 23 [/tex]

Reorder the terms:
[tex]-9 + 4x = 23 [/tex]

Solving:
[tex]-9 + 4x = 23 [/tex]

Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
[tex]-9 + 9 + 4x = 23 + 9 [/tex]

Combine like terms: [tex]-9 + 9 = 0[/tex]
[tex]0 + 4x = 23 + 9 [/tex]
[tex]4x = 23 + 9 [/tex]


Combine like terms: [tex]23 + 9 = 32[/tex]
[tex]4x = 32 [/tex]

Divide each side by '4'.
[tex]x = 8 [/tex]

Simplifying:
[tex]x = 8 [/tex]
