-4x + 11y = 15<br><br> x=2y<br><br><br> Solve for y and x
Stolb23 [73]

Answer:

to find Y

-4x + 11y = 15

x - 2y = 0

.

equal= -3x + 9y= 15

since x=2y

-3(2y) + 9y = 15

-6y + 9y =15

3y = 15

y = 15/ 3

y = 5

.

to find x

using x=2y

since

y=5

,therefore

x= 2(5)

x= 10

I need help on this question 5(x - 4) = 12
Wewaii [24]
<h2><u>Answer:</u></h2><h2><u />\boxed{\frac{32}{5},~ 6\frac{2}{5} ~, 6.4}<u /></h2><h2><u /></h2><h2><u>Solution Steps: </u></h2><h3>- Steps for solving linear equations - </h3>

______________________________

<h2><u> </u></h2><h3>1.) <u>Divide both sides by 5: </u></h3>
  • 5 ÷ 5= Cancels out
  • <u />12 ÷ 5= \frac{12}{5}

<em>  - I changed  </em>\frac{12}{5}<em> to a fraction instead, and you'll see why on the next step. </em>

<h2><em><u /></em></h2><h3>2.) <u>Add 4 to both sides:</u></h3>
  • -4+4= Cancels out
  • 4=\frac{20}{5}

<em>  - 4 in fraction form would best be </em>\frac{20}{5}<em> in this situation. </em>

<h2><em><u /></em></h2><h3>3.) <u>Add: </u></h3>
  • \frac{12}{5} + \frac{20}{5} = \frac{32}{5}

<em> - Since </em>\frac{12}{5}<em> and </em>\frac{20}{5}<em> have the same denominator, all you have to do is add the numerators. </em>

<h2><u /></h2><h3>4.) <u>Simplify:</u></h3>
  • Improper fraction form: \frac{32}{5}
  • Mixed number form: 6\frac{2}{5}
  • Decimal form: 6.4
<h2><u /></h2>
