1/5x-2/3y=30 when y=15

dolphi86 [110]

Answer:

Step-by-step explanation:

<u>Step 1: Set y to 15 and solve</u>

<u /> $\frac{1}{5}x - \frac{2}{3}*15=30$

$\frac{1}{5}x-10=30$

<em>Add 10 to both sides</em>

<em /> $\frac{1}{5}x-10+10=30+10$

$\frac{1}{5}x=40$

<em>Multiply both sides by 5</em>

<em /> $\frac{1}{5}x*\frac{5}{1}=40*\frac{5}{1}$

$x=200$

Answer: $x=200$
