T +7 is Tim's age in 7 years
three times what it was 19 years ago = 3(t-19)

so equation should be:
t + 7 = 3(t - 19)

-8x-27=-7\left(1+2x\right)+2x

Answer:

$x=5$

Step-by-step explanation:

$-8x-27=-7\left(1+2x\right)+2x$

Expand:

$-8x-27=-7\times 1-7\times 2x+2x$

$-8x-27=-7-12x$

Add 27 to both sides:

$-8x-27+27=-7-12x+27$

$-8x=-12x+20$

Add 12x to both sides:

$-8x+12x=-12x+20+12x$

$4x=20$

Divide both sides by 4:

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Well, if you have a word problem for example:

Maria has 24 backpacks and 12 textbooks. She needs to fit all the books in the backpacks evenly. How will she do that?

So you could do 24 ÷ 12 = 2 textbooks per backpack OR

Add 12 together until you get to 24, 12 + 12 = 24

So all you need to do is show your work and how you solved both solutions to any type of problem. (Hope this was helpful!)
