if a=2, b=3, and c=-4
a+b+c
2+3+(-4) = 5-4 =1
x/3 = 6
x=18
Ben is 7 years older than Sam. Sam is 12. How old is Ben?
19
a-b-c
2-3-(-4) = 2-3+4 = -1+4 = 3
2x + 4 = 14
x =5
I have a number, I add 9 to it, and I get 20. What's the number?

abc
2x3x-4 = -24
5x - 8 = 37
x=9
I have a number, I divide it by 2, I subtract 3 and I get 3. What' the number
12
2a + 3b - 4c
4 + 9 - (-16) = 4+9+16 = 29
2x + 6 =9
x = 3/2
A line has 3 angles 8p, 3x, and 2x. Make an equation and find x
180 = 20+3x+2x
x=20
(3a (2c)) / 2b
(6 x -8) / 6 = -48/6 = -8
4x - 7 =10
17/4
A triangle has angles x, 3x, and 40. Make an equation and solve for x
x = 35
