Question

1. $5 + \frac{h}{4} = 4$

$\frac{h}{4} \times 4 = -1 \times 4 \quad h=4$

1. $104 = -7r + 4$
2. $0 = -7 + \frac{k}{2}$

Explanation:

Step1: Isolate $\frac{h}{4}$ term

Subtract 5 from both sides:
$\frac{h}{4} = 4 - 5$
$\frac{h}{4} = -1$

Step2: Solve for $h$

Multiply both sides by 4:
$h = -1 \times 4$
$h = -4$

Step3: Isolate $-7r$ term

Subtract 4 from both sides:
$104 - 4 = -7r$
$100 = -7r$

Step4: Solve for $r$

Divide both sides by $-7$:
$r = \frac{100}{-7}$
$r = -\frac{100}{7}$

Step5: Isolate $\frac{k}{2}$ term

Add 7 to both sides:
$0 + 7 = \frac{k}{2}$
$7 = \frac{k}{2}$

Step6: Solve for $k$

Multiply both sides by 2:
$k = 7 \times 2$
$k = 14$

Answer:

$h = -4$
$r = -\frac{100}{7}$
$k = 14$
