1 answer

Solving the equations:

1) (x)/(3.2)=1.8
To solve for x, multiply both sides of the equation by 3.2:
x = 1.8 * 3.2
x = 5.76

2) 1.8x=3.2
To solve for x, divide both sides of the equation by 1.8:
x = 3.2 / 1.8
x = 1.7778

3) -(3)/(4)x=(5)/(2)
To solve for x, divide both sides of the equation by -3/4:
x = (5/2) / (-3/4)
x = (5/2) * (-4/3)
x = -10/3

4) (5)/(2)x=-(3)/(4)
To solve for x, divide both sides of the equation by 5/2:
x = -(3/4) / (5/2)
x = -(3/4) * (2/5)
x = -3/10

5) -3.2x=0.64
To solve for x, divide both sides of the equation by -3.2:
x = 0.64 / -3.2
x = -0.2

6) (x)/(4)=-0.05
To solve for x, multiply both sides of the equation by 4:
x = -0.05 * 4
x = -0.2

7) (3)/(8)x=1
To solve for x, divide both sides of the equation by 3/8:
x = 1 / (3/8)
x = 1 * (8/3)
x = 8/3

8) (1)/(3)x=(1)/(8)
To solve for x, multiply both sides of the equation by 3/1:
x = (1/8) * (3/1)
x = 3/8
