The value of variable x in the equation is 6.1
what are variables?
Variables are numbers represented with letters in an equation. Therefore, we have to find the variable x of the equation.
−4.5(x−8.9) = 12.6
open the bracket
-4.5x + 40.05 = 12.6
-4.5x = 12.6 - 40.05
-4.5x = -27.45
divide both sides by -4.5
x = -27.45 / -4.5
x = 6.1
