Hi!
3x - 30 = x + 10
<h3>Solve by isolating x on one side. </h3><h3>Add 30 to both sides. </h3>
3x - 30 + 30 = x + 10 + 30
3x = x + 40
<h3>Subtract x from both sides. </h3>
3x - x = x - x + 40
2x = 40
<h3>Divide by 2 on both sides</h3>
2x/2 = 40/2
<u>x = 20</u>
<h2>The answer is x = 20</h2>
Hope this helps! :)

This is actually really simple algebra. All you need to know is that Y= Mx + B
and M BEING YOUR SLOPE good luck
Answer:
9/15=3/5
so 3/5 is equivalent fraction of the 9/15
X : number of tacos they sell per day. ...... profit = y = 3.25 × x - 210 ......inequality. y > 0. so. x > 210/3.25 = 840/13 = 64. ......so the taco stand must sell at least 65 tacos for making profit.
First add 10 on both sides. So it will be v = 1.
