Answer: x = 38.4

Step-by-step explanation:

7-x/3 = -1-x/8

1. Add 1 to both sides

8-x/3 = -x/8

2. Add x/3 to both sides

8 = x/3 - x/8

3. Multiply x/3 by 8/8 and x/8 by 3/3 to get the same number under the quotient

8 = 8x/24 - 3x/24

4. calculate the difference between 8x/24 - 3x/24

8 = 5x/24

5. Multiply both sides by 24/5, and there is the answer

38.4 = x

Solve the equation 3/y = 4/5

netineya [11]

Step-by-step explanation:

Step 1: Cross Multiply

$\frac{3}{y} = \frac{4}{5}$

$5(3) = 4(y)$

$15 = 4y$

Step 2: Divide both sides by 4

$15 / 4 = 4y / 4$

$3.75 = y$

Answer: $y = 3.75$
