Me solve this! i have tried multiple times but it never checks out! it's a systems of equations- substitution question!

x = -3, y = -4

Step-by-step explanation:

Double the first equation to get 6x - 2y = -10

Now just add the two together and get x = -3. Plug this back in to get y = -4.

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
