3. what to find????
4. 1/8

Answer 2

Answer:

The values of $w=-75$, $x=\frac{3}{4}$ , $y=200$, $a=-\frac{1}{8}$.

Tip:

• Simplify each side of the equation by removing parentheses and combining like terms.

• Use addition or subtraction to isolate the variable term on one side of the equation.

• Use multiplication or division to solve for the variable.

Step

Step 1 of 4:

We have equation :  $\frac{w}{3}+5=-20$

Subtracting $5$ both sides:

$\frac{w}{3}+5-5=-20-5\\\\\frac{w}{3}=-25$

Now, multiplying $3$ both sides, we get

$w=-25\times 3\\w=-75$

Step 2 of 4:

We have equation :  $\frac{3}{x}+5=9$

Subtracting $5$ both sides:

$\frac{3}{x}+5-5=9-5\\\\\frac{3}{x}=4$

Now, multiplying $x$ both sides, we get

$x\times \frac{3}{x}=4x\\\\3=4x\\\\x=\frac{3}{4}$

Step 3 of 4:

We have equation :  $\frac{y}{10}-12=8$

Adding $12$ both sides:

$\frac{y}{10}-12+12=8+12\\\\\frac{y}{10}=20$

Now, multiplying $10$ both sides, we get

$y=20\times 10\\y=200$

Step 4 of 4:

We have equation :  $16a-3=-5$

Adding $3$ both sides:

$16a-3+3=-5+3\\\\16a=-2$

Now, dividing $16$ both sides, we get

$\frac{16a}{16}=-\frac{2}{16}\\\\a=-\frac{1}{8}$
