5.8+4.1-12.6+x-8.9=-4.6
We move all terms to the left:
5.8+4.1-12.6+x-8.9-(-4.6)=0
We add all the numbers together, and all the variables
x-7=0
We move all terms containing x to the left, all other terms to the right
x=7

4.5(x−8.9)=12.6

Step 1: Simplify both sides of the equation.4.5(x−8.9)=12.6(−4.5)(x)+(−4.5)(−8.9)=12.6

(Distribute)4.5x+40.05=12.6

Step 2: Subtract 40.05 from both sides.4.5x+40.05−40.05=12.6−40.054.5x=−27.45

Step 3: Divide both sides by -4.5.4.5x−4.5=−27.45−4.5
x=6.1
