Collect like terms by calculating the sum or difference of their coefficients
(−24−98)x
Subtract the numbers
−122x
−122x−9=0
Move the constant to the right-hand side and change its sign
−122x=0+9
Removing 0 doesn't change the value,so remove it from the expression
−122x=9
Change the signs on both sides of the equation
122x=−9
Divide both sides
122122x=122−9
Divide the numbers
x=122−9
