Mathematics

- 4 ( 7a + 7 ) - 2a = 92

- 28a - 28 - 2a = 92

- 28a - 2a - 28 = 92

Collect like terms

- 30a - 28 = 92

Add both sides 28

- 30a - 28 + 28 = 92 + 28

- 30a = 120

Divide both sides by - 30

- 30a ÷ - 30 = 120 ÷ - 30

<h2><em>a</em><em> </em><em>=</em><em> </em><em>-</em><em> </em><em>4</em><em> </em></h2>

• Number of psychology textbooks sold: The number is not correct
diamong [38]

Answer:

209 biology books and 125 psychology books were sold.

Step-by-step explanation:

x = biology books y = psychology books

334 = x + y

x = y + 84

x - y = 84

y = x - 84

Using these systems of equations, we can see that (209,125) is the only possible answer. Elimination, substitution, or guess and check are all viable methods to solve this problem. I can explain further if needed! :)

If jimmy has 3 papers and bob gives jimmy 336 papers then richard steals 124 papers how many papers does jimmy have?
Jobisdone [24]

Since Jimmy has 3 papers and Bob gave him 336. Richard steals 124 papers leaving Jimmy with 215 papers.

The equation looks like this:

(3+336) - 124 = 215

<em>btw richards mean for stealing jimmy's papers :D</em>
