Elimination method 2x -3y=7 3x-2y=13
strojnjashka [21]

Answer:

x = 5 and y = 1 or (5, 1)

Step-by-step explanation:

2x -3y=7

3x-2y=13

Multiply (1st) equation by 3 and (2nd) equation by 2

6x -9y=21

6x-4y=26

-5y = - 5

y = 1

Substitute y = 1 into 2x -3y=7

2x -3(1)=7

2x - 3 = 7

2x = 10

x = 5

Answer

x = 5 and y = 1 or (5, 1)

Now, that we know he reads 20 pages per hour, we just divide 230 by 20 to find the amount of hours. Our answer comes out to 11.5 hours.
