Determine whether -2 is the solution of the equation.
3x-4=6(x+2)​

12 servings. 4 times 3= 12

answer:

equation:  

solve for n:   n = 112

step-by-step explanation:

to first set up the equation, you need to look at the verbal description and translate into numbers and operations:

'three fourths a number' =  

'plus 8' = + 8

'is' =

'20 less' = - 20

'the number' = n

put the expressions together:

'three fourths a number plus 8':  

'20 less than the number': n - 20

set them equal to each other and solve:

add 20 to both sides:

subtract from both sides:

multiply both sides by :

solve for n:   n = 112
