Solve 5x-9=26.

When a question asks us to solve an equation, it is asking us to find the value of x. We need to rearrange so that x is on one side of the equals sign, and everything else is on the other. First, we need to add 9 to each side of the equation. This gives us 5x-9+9=26+9 so 5x=35. Now we divide both sides of the equation by 5. 5x/5=35/5 so x=7. We have solved the equation.To check our answer is right, we can substitute the answer back into the original equation. If we are correct, x=7 into 5x-9 should equal 26. Let's check: x=7 so 5x7=35. 35-9=26 which is the answer we were looking for. So our answer is correct!
