Question

Solve for $\uptext{x}$ and $\uptext{y}$ . Round your answer to the nearest hundredth.

Answer

The first step to do is solve for a variable. Let's solve for $\uptext{x}$ first.

Now we subtract from each side.

Now we divide by

$x = \frac{14 y}{3} + \frac{95}{3}$

Now since we found $\uptext{x}$ , we can plug this into the other equation and find $\uptext{y}$ .

$\frac{532 y}{3} + \frac{3610}{3} + 13 y = 28$

Now we solve for $\uptext{y}$ .

$\frac{571 y}{3} = -1175.3333333333333$

Now we divide by $\frac{571}{3}$

Now round to the nearest hundredth.

Now since we have a value for $\uptext{y}$ , we plug this into the first equation and find $\uptext{x}$ .

Now we add to each side.

Now we divide by

Now round to the nearest hundredth.

Question

Solve for $\uptext{x}$ and $\uptext{y}$ . Round your answer to the nearest hundredth.

Answer

The first step to do is solve for a variable. Let's solve for $\uptext{x}$ first.

Now we subtract from each side.

Now we divide by

$x = - \frac{21 y}{8} - \frac{47}{8}$

Now since we found $\uptext{x}$ , we can plug this into the other equation and find $\uptext{y}$ .

$- \frac{147 y}{4} - \frac{329}{4} + - 26 y = -68$

Now we solve for $\uptext{y}$ .

$- \frac{251 y}{4} = 14.25$

Now we divide by $- \frac{251}{4}$ .

Now round to the nearest hundredth.

Now since we have a value for $\uptext{y}$ , we plug this into the first equation and find $\uptext{x}$ .

Now we add to each side.

Now we divide by

Now round to the nearest hundredth.

Answer

The first step to do is solve for a variable. Let's solve for $\uptext{x}$ first.

Now we subtract from each side.

Now we divide by

$x = \frac{11 y}{16} - \frac{61}{32}$

Now since we found $\uptext{x}$ , we can plug this into the other equation and find $\uptext{y}$ .

$\frac{429 y}{16} - \frac{2379}{32} + - 34 y = 53$

Now we solve for $\uptext{y}$ .

$- \frac{115 y}{16} = 127.34375$

Now we divide by $- \frac{115}{16}$ .

Now round to the nearest hundredth.
