- 5x + 2y = 9<br> y = 7x
Lorico [155]

Answer:

<h2><u>x = 1</u></h2>

Explanation:

- 5x + 2y = 9

  • y = 7x
  • <u>Insert 7x For 'y'</u>

- 5x + 2(7x) = 9

  • <u>Remove Parenthesis</u>

-5x + 2 · 7x = 9

  • <u>Multiply: 2 · 7 = 14</u>

-5x + 14x = 9

  • <u>Add: -5x + 14x = 9x</u>

9x = 9

  • <u>Divide Both Sides By 9</u>

9x ÷ 9 = 9 ÷ 9

<h2><u>x = 1</u></h2>
