Well you can solve two step equations by multiplying or adding or subtracting or dividing by the number and put a n on the answer because there is only one n in equatioN see the solve the modle
Let x = adult tickets
Let y = children's tickets
x + y = 800
8x + 4y = 4,400
From the first eq, x = 800 - y, plug this in to the second eq
8(800-y) + 4y = 4,400
6400 - 8y + 4y = 4,400
2000 = 4y
500 = y
x = 800 - 500
x = 300
300 adult tickets were sold.
Your answer is C, not B.
-3x + 4 + 2x -2 combined like terms.
-1x + 2
-x - 2. Simple Math.
Equation: 
Since there aren't any like terms and it can't be factored, your answer would be:
Hope this answer helped you!
The answer is
B. 13ab
5ab+9ab-ab
=(5ab+9ab)-ab
14ab-ab
=13ab
Hope it helped : )
