Question

Given the equation 4(3n-7) = -19, what is the first step you could use to solve for n?​

Answer 1

3/4

You would have to divide both sides by 4

Explanation:

`(4(3n-7))/(4) =(-19)/(4)` ( divide both sides by 4 )

`3n-7= -(19)/(4)` ( simplify )

`3n-7+7=-(19)/(4) +7` ( add 7 to both sides )

`3n=(9)/(4)` ( simplify )

`(3n)/(3) =((9)/(4) )/(3)` ( divide both sides by 3 )

`n=(3)/(4)`

Answer 2

3/4

Explanation:

4(3n-7)=-19

3n-7=-19/4

3n=-19/4+7

3n=-19/4+28/4

3n=9/4

n=(9/4)/3

n=(9/4)(1/3)

n=9/12

simplify

n=3/4
