Basic Solving
2 + 2
4
12 more than x
12 + x or x + 12
3x = 9
x = 3
-5 - (-12)
7
2 = (x-4)/3
10
3 + 5 * 8
43
Thirteen less than a number n
n - 13
4b + 2 =10
b = 2
(-3)(2)(-4)
24
5(x+7) - 5 = 60
x = 6
12 - 2(4+3)
-2
The sum of 7 and a number, minus 12
(7 + n) - 12
12x/6 = 6
x = 3
17 - 12(4 - 3) + 2(-2)
1
5x + 3x - 2x - 7 = 17
4
2/3 * 4/8
1/3
The product of 4 and a number less than 8
8 - 4n
2(x+4) = 32
x = 4
(12 - 3)/3 +7
10
2x - 12 = 3 - 3x
1/2 + 1/3
5/6
The sum of three times a number and two less than four times a number
3n + 4n - 2
7n-2
1/2x - 5 = 3
16
24(12/6) / (42 - 36) + 3(4 + 7 * 3)
81
6x + 2(x+4) = 4 (4x - 3) - 4
