**Solve by Elimination<br> 3 + 2x - y = 0<br> -3-7y = 10x<br> 7) x =<br> 8) y =
timofeeve [1]
Answer:

Explanation:

3 + 2x - y = 0
Or 2x - y = -3 (1)

-3-7y = 10x
Or -10x - 7y = 3 (2)

2x - y = -3 (1)
-10x - 7y = 3 (2)
———————

Multiply 5 to (1)

5(2x - y = -3)
-10x - 7y = 3
———————
10x - 5y = -15
-10x - 7y = 3
———————
-12y = -12
y = -12/-12
y = 1

Plug y value in (1)

2x - 1 = -3
2x = -3 + 1
2x = -2
x = -2/2 = -1

Therefore, x = -1 and y = 1

<h3><u>Answer</u><u>:</u></h3>

7 \frac{1}{2}

<h3><u>Explan</u><u>ation</u><u>:</u></h3>

First, convert any mixed numbers to fractions. An easy way to convert:

4 \frac{1}{2}  = 4 \times 2 + 1

<h3>=</h3>

\frac{9}{2}  \div  \frac{3}{5}

Then, apply the fractions formula for division.

\frac{9 \times5 }{2 \times 3}  =  \frac{45}{6}

Then, simplify.

\frac{45}{6}   = 7 \frac{1}{2}
