What is the first step in solving this equation? 3(2x + 6) – 4x = 2(5x – 2) + 6?

Which number produces a rationale number when multiplied by 1/5

(05.03 mc) part a: explain why the x-coordinates of the points where the graphs of the equations y = 4x and y = 2x−2 intersect are the solutions of the equation 4x = 2x−2. (4 points) part b: make tables to find the solution to 4x = 2x−2. take the integer values of x between −3 and 3. (4 points) part c: how can you solve the equation 4x = 2x−2 graphically? (2 points)

Could someone me with this question i’ve been stuck on it for 20 minutes
