1. -10=xy+z, solve for x please? 2. h-4/j =k, solve for j please?

ANEK [815]

Answer:

$x=\frac{-10-z}{y}$

Step-by-step explanation:

1 Subtract z from both sides.

$-10-z=xy$

2 Divide both sides by y

$\frac{-10-z}{y} =x$

3 Switch sides.

$x=\frac{-10-z}{y}$

2nd question

Answer: $j=-\frac{4}{k-h}$

Step-by-step explanation:

1 Subtract h from both sides

$-\frac{4}{j} =k-h$

2 Multiply both sides by j.

$-4=(k-h)j$

3 Divide both sides by k−h.

$-\frac{4}{k-h}=j$

4 Switch sides.

$j=-\frac{4}{k-h}$
