One Step Equations
Solve: x + 9 = 21
x = 12
3k + 4k + 8 = 22
k = 2
Solve: -7x - 12 = 16
x = -4
V = lwh
Find v when l = 2, w = 3 and h = 4
2 x 3 x 4 = 24
18 + s = 12
x = -6
x + 4 + 6 = 23
x = 13
21 = 8x + 5
x = 2
V= lwh
find w when v = 24, l = 2 and h = 3
24 = (2)(3)(w)
24 = 6w
4 = w
12 = z - 5
z = 17
3z + 5 - 2z = 9
z = 4
n/3 + 9 = 12
n = 9
P = 2l + 2w
Find P when l = 4 and w = 8
P = 2(4) + 2(8)
P = 8 + 16
P = 24
-7 = -1 + a
a = -6
Simplify 4(a + 2)
4a + 8
54/x = 6
9 = x
P = 2l + 2w
Find l when p = 50 and 2 = 5
50 = 2l + 2(5)
50 = 2l + 10
40 = 2l
l = 20
h + 23 = 11
h = 3
Simplify -10(c + 3)
-10c + -30
3 - x/9 = 1
x = 18
A = lw
Find l when A = 12 and w = 3
12 = 3l
4 = l
