Which of the following is the best first step to convert the following equation to slope intercept form?
2-4y =-12

y=7/2 in decimal form 3.500

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2-4*y-(-12)=0

Pull out like factors :

  14 - 4y  =   -2 • (2y - 7)

  Solve  :    2y-7 = 0  

Add  7  to both sides of the equation :  

                     2y = 7

Divide both sides of the equation by 2:

                    y = 7/2 = 3.500

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
