Mathematics
1 answer:
makvit [3.9K]3 years ago
3 0

Answer:

y=6

Step-by-step explanation:

4(2y-3)-2y=24

Distribute

8y -12 -2y = 24

Combine like terms

6y -12 = 24

Add 12 to each side

6y-12+12 =24+12

6y = 36

6y/6 =36/6

y = 6

Olivia family drove to Disney land For spring break. Her mom and dad shared the driving duties for a total of 14 hours. her mom
Troyanec [42]

For this case we propose a system of equations:

x: Variable that represents the amount of hours that Olivia's mother drove

y: Variable that represents the amount of hours that Olivia's father drove

So, we have:

x + y = 14\\65x + 60y = 895

From the first equation we have:

x = 14-y

Substituting in the second equation:

65 (14-y) + 60y = 895\\910-65y + 60y = 895\\-5y = 895-910\\-5y = -15\\y = \frac {15} {5}\\y = 3

Thus, Olivia's father drove 3 hours.

x = 14-3 = 11

Olivia's mother drove 11 hours.

Answer:

(x, y) :( 11,3)
