<h3>
Solution (1):</h3>
<u>Given:</u>
<u>Multiplying y = 3x - 5 by 2:</u>
y = -6x - 5
y = -6x - 5
<u>Adding both equations:</u>
<u>Dividing 3 both sides:</u>
<u>Substitute the value of y into any equation.</u>
- y = -6x - 5
- => -5 = -6x - 5
- => 0 = -6x
<u>Divide -6 both sides.</u>
<h3>
Solution (2):</h3>
<u>Given:</u>
<u>Add both the equations.</u>
y = -8x + 7
<u>Divide 2 both sides.</u>
- 2y = -2
- => 2y/2 = -2/2
- => y = -1
<u>Substitute the value of y into any equation.</u>
<u>Add 9 both sides.</u>
- => -1 + 9 = 8x - 9 + 9
- => 8 = 8x
<u>Divide 8 both sides.</u>
<h3>
Solution (3):</h3>
<u>Given:</u>
<u>Reorganize the first equation.</u>
- -x + 6y = 21
- => 6y = x + 21
<u>Multiply the first equation by 5.</u>
y = -5x + 12
y = -5x + 12
<u>Add both the equations.</u>
<u>Divide 31 both sides.</u>
- 31y = 117
- => 31y/31 = 117/31
- => y = 117/31
<u>Substitute the value of y into any equation.</u>
- -x + 6y = 21
- => -x + 6(117/31) = 21
- => -x + 702/31 = 651/31
<u>Subtract 702/31 both sides.</u>
- => -x = 651/31 - 702/31
- => -x = -51/31
- => x = 51/31
Y=4/x-3/x
y=1x(mean X)
So,y = x
It’s the same so 36.6 because if they are vertical angles both sides are congruent
Answer:
It would take Mike 10 minutes to eat 35 hotdogs. Mike can eat 122.5 hotdogs in 35 minutes.
Step-by-step explanation:
21 hotdogs / 6 minutes = 3.5 hotdogs per minute
35 / 3.5 = 10 minutes
35 (3.5) = 122.5 hotdogs
