x = 0.67
x = 0.67

x = 7
x = 7

x = 6.67
x = 6.67

x = 9.5

Answer 3

0.72 = 0.4x + 0.56

0.72 - 0.56 = 0.4x

0.16 = 0.4x

0.16/0.4 = x

0.4 = x

Answer 4

2(1.5x - 7) = 6

3x - 14 = 6

3x = 6 + 14

3x = 20

x = 20/3

Answer 5

2(1.5x - 7) = 6

Distribute the 2:

3x - 14 = 6

Add 14 to both sides:

3x = 20

Divide by 3:

x = 20/3

So, x = 6.67.
