7n — 4 = 31

What is the answer

n=5

Step-by-step explanation:

Simplifying 7n + -4 = 31

Reorder the terms: -4 + 7n = 31

Solving -4 + 7n = 31 Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right. Add '4' to each side of the equation.

-4 + 4 + 7n = 31 + 4

Combine like terms: -4 + 4 = 0 0 + 7n = 31 + 4 7n = 31 + 4 Combine like terms: 31 + 4 = 35 7n = 35

Divide each side by '7'. n = 5

Simplifying n = 5

7n-4=31 and you need an answer for n so

n = 5 hope this helps!

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
