Answer:

x= -2, y = -3

Step-by-step explanation:

1. substitute x = 4+2y in the first equation: $\begin{bmatrix}2\left(4+2y\right)+y=-7\end{bmatrix}$

simplify it : $\begin{bmatrix}8+5y=-7\end{bmatrix}$

2. isolate y in 8 + 5y = -7 --> 5y = -7 - 8 -->

3. solve for y: 5y = -15 --> y = -15/5 --> y= -3

4. solve for x: x = 4 + 2y

x = 4 + 2(-3)

x = 4 + (-6)

x = -2

What is x/9 = 9/27 help plz

Irina18 [472]

<h3><u>QUES</u><u>TION</u><u>:</u><u> </u></h3>

what is x/9 = 9/27 help plz

<h3><u>ANSWER</u><u> </u><u>AND</u><u> </u><u>SOLU</u><u>TION</u><u>:</u><u> </u></h3>

SOLVING FOR X

<u>Reduce</u><u> </u><u>first</u><u> </u><u>the</u><u> </u><u>fraction</u><u> </u><u>with</u><u> </u><u>9</u>

$\large \sf = \dfrac{x}{9} = \dfrac{ \cancel9}{ \cancel{27}}$

<u> $\large \sf = \dfrac{x}{9} = \dfrac{1}{3}$ </u>

<u>Now</u><u> </u><u>simpli</u><u>fy</u><u> </u><u>using</u><u> </u><u>cross-multiply</u>

<u> $\large \sf = \dfrac{3x}{9} = 1$ </u>

<u> $\large \sf = 3x = 1 \times 9$ </u>

<u> $\large \sf = 3x = 9$ </u>

<u>Lastly</u><u> </u><u>divide</u><u> </u><u>both</u><u> </u><u>sides</u>

<u> $\large \sf = 3x \div 3 = 9 \div 3$ </u>

<u> $\large \sf = x = 9 \div 3$ </u>

<u> $\large \sf = x = 3$ </u>

<h3><u>FINAL</u><u> </u><u>ANSWER</u><u>:</u></h3>

$\huge \orange{ \underline{ \boxed{ \sf{x = 3}}}}$

HOPE THIS HELP YOU! HAVE A NICE DAY!
