Question

If y = 87.5, what is the value for x? 300x + 300 x plus StartFraction 500 over 7 EndFraction y equals 10,000.Y = 10,000 300x + 300 x plus StartFraction 500 Over 7 EndFraction y equals 10,000.(87.5) = 10,000 300x + 6,250 = 10,000

Answer 1

Answer:

$x =12.5$

Step-by-step explanation:

Given

$300x + \frac{500}{7}y =10000$

$y = 87.5$

Required

Find x

Substitute $y = 87.5$ in $300x + \frac{500}{7}y =10000$

$300x + \frac{500}{7}*87.5 =10000$

$300x + 500*12.5 =10000$

$300x + 6250=10000$

Collect like terms

$300x =10000-6250$

$300x =3750$

Divide by 300

$x =12.5$
