24-x=3 add x to both sides.....subtract 3 from both sides
21 = x
[ 3 - 2 ] / 2 x 100% =
1 / 2 x 100% =
50%
3 + 1/3 = 10/3 7 + 1/2 = 15/2 ...so we have...
(10/3)y = 15/2 multiply both sides by 3/10
= (15/2)(3/10) = 45 / 20 = 9 / 4
a/4+3 = 16 subtract 3 from both sides
a/4 = 13 mutliply both sides by 4
a = 52
[7 * 3 - 6 ] * 5 =
[ 21 - 6 ] * 5 =
[15 ] * 5 =
75
188 / 4 =
94 / 2 =
47 cm
0.2(x+50)-6=0.4(3x+20) simplify
.2x + 10 - 6 = 1.2x + 8
.2x + 4 = 1.2x + 8 subtract .2x, 8 from both sides
- 4 = x
13 in x [ 1 meter / 39.37 in] ≈ .33m
13 in x [1ft /12 in] = 13/12 ft ≈ 1.0833....... ft
[We don't need to worry about cms.]
