One-Step and Two-Step
(2/3)x = 2
x = 3
|x| = 21
x = 21
x = -21
A number increased by 12 is 25
x + 12 = 25
(3/5)x = 12
x = 20
|x| + 7 = 31
x = 24
x = -24
Twice a number decreased by 18 is 9
2x - 18 = 9
6w - y = 2z for w
w = (2z + y) / 6
-(4/5)x = 18
|x| + 9 = 2
No Solution
twice a number plus 7 is equal to 21
2x + 7 =14
mx + 4y = 3c for x
x = (3c - 4y)/m
12 - 5x = -33
x = 9
|x + 6| = 18
x = 12
x = -24
7 plus a number times the quantity of a number minus 3 is the same as 53
7 + n(n - 3) = 53
(m - x) /a = b for m
m = ab + x
1/2x + 3/4 = 5/8
x = -1/4
3|x + 15| + 8 = 32
x = -7
x = -23
the product of 4 and the quantity of a number minus 3 equals 12
4(x-3)=12
(a + b)/c = d, for a
a = cd - b
