<em>x = - 2</em>
<em>y = 5</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>2x + 9 = y</em>
<em>y = - 4x - 3</em>
<em>
</em>
<em>equality</em>
<em>2x + 9 = - 4x - 3</em>
<em>2x + 4x = - 9 - 3</em>
<em>6x = - 12</em>
<em>x = - 12 : 6</em>
<em>x = - 2</em>
<em>replace x = - 2</em>
<em>2(-2) + 9 = y</em>
<em>- 4 + 9 = y</em>
<em>y = 5</em>

Based on the information given, the simple interest rate that will be earned will be 13.6%.
- Principal = $5250
- Simple Interest = $6500- $5250 = $1250
- Time = 21 months = 1.75 years.
Simple Interest = PRT / 100
1250 = (5250 × 1.75 × R) / 100
Cross multiply
125000 = 9187.5R
R = 125000 / 9187.5
R = 13.6%
