Answer:

1.3n + 9.6

Step-by-step explanation:

3.4n + 9.6 - 2.1n

So you can rearrange it to make it visually easier (but it's not needed)

3.4n - 2.1n + 9.6

Subtract like terms

1.3n + 9.6

Hello!

Explanation:

First, you had to do is switch sides of an equation.

$-12(x+5)=144$

Then you divide by -12 from both sides of an equation.

$\frac{-12(x+5)}{-12}= \frac{144}{-12}$

Simplify.

$144/-12=-12$

$x+5=-12$

Next, subtract by 5 from both sides of an equation.

$x+5-5=12-5$

Simplify.

$12+5=17$

Answer: → $\boxed{x=-17}$

*The answer must have a negative sign.*

Hope this helps!

Choose the correct words from the drop-down menu to make a true statement about the system of equations.

Artist 52 [7]

Answer:

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{3}$ x + 2 → (1)

- x + 3y = 6 → (2)

Substitute y = $\frac{1}{3}$ x + 2 into (2)

- x + 3( $\frac{1}{3}$ x + 2) = 6 ← distribute left side

- x + x + 6 = 6, that is

6 = 6 ← True

This statement indicates the system has infinitely many solutions
