To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.

Elena plans to ride her bicycle 5 miles to a park and then ride several times
Aneli [31]

Option A

Elena need to ride around the  loop four or more times

<em><u>Solution:</u></em>

Given that Elena plans to ride her bicycle 5 miles to a park and then ride several times  around a loop in the park that is 3 miles long

Then she will ride the same way  home

She wants to ride a total of at least 22 miles

<em><u>Given inequality is:</u></em>

3t + 10 > 22

Where "t" is the number of times Elena rides around the loop

<em><u>Solve fot "t" in given inequality</u></em>

3t + 10 > 22

Subtract 10 both sides

3t + 10 - 10 > 22 - 10

3t > 12

Divide by 3 both sides

t > 4

The solution is all real numbers greater than or equal to 4

Which means 4 or more times

Therefore, Option A is correct.
