describe the relationship between n and 4 that will make the value of the expression 7× n/4 greater than 7
Norma-Jean [14]
So set up an equation!

7* n/4 > 7

So trying to get the variable alone...

n/4 > (7/7) aka 1
n> 1*4
n> 4

Try it out!

7* 6/4 = 42/4 = 21/2= 10 and 1/2

It is greater than 7

How do you find a linear equation
Tasya [4]
Flip equation
- 12x + 96 = y - 11
add -96 to both sides
- 12x + 96 +  - 96  =   \\ y - 11  +  - 96 - 12x = y - 107
divide both sides by -12
\frac{ - 12x}{12}  =  \frac{y - 107}{12}
ANSWER
\frac{ - 1}{12} y +  \frac{107}{12}
