what is the value of s in the equation 4(2s − 1) = 7s + 12?

12
16
32
34

could you also do a step by step explanation so that i understand and if i get a similar question on a test i will know. i will reward with 65 points and mark brainliest

We need to get the variable on one side (usually the left side) and all other constants (like numbers and certain symbols like ) on the opposite side of the variable (usually the right side).

4(2s - 1) = 7s + 12 // Our starting equation
8s - 4 = 7s + 12    //   Distribute the 4 across the 2s and the -1
s - 4 = 12             //    Subtract both sides by 7s
s = 16                 //     Add both sides by 4

The variable s is equal to 16.
