Multi step equation and check 12x+3-1=35

11/4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12x+3−1=35

12x+3+−1=35

(12x)+(3+−1)=35(Combine Like Terms)

12x+2=35

12x+2=35

Step 2: Subtract 2 from both sides.

12x+2−2=35−2

12x=33

Step 3: Divide both sides by 12.

12x / 12 = 33 / 12x =

11 / 4

answer: 25.4 units

step-by-step explanation: radius = 12.7 units
