Solve the system by substitution.
3x + 1 = y
10x – 4y = -8
Pls help

x = 2

y = 7

Step-by-step explanation:

3x + 1 = y

10x - 4y = -8

10(2) - 4(7) = -8

20 - 28 = -8

-8 = -8

3(2) + 1 = (7)

6 + 1 = 7

7 = 7

x = 2, y = 7, (2,7) are coordinates

Step-by-step explanation:

So your going to replace "y" in the second equation, for the value of "y" described in the first.

10x-4(3x+1)= -8

10x-12x-4 = -8

10x-12x = -4

-2x = -4

x = 2

Now we solve for "y" by substituting with the value of "x" we just found. So it's...

3(2) + 1 = y

6+1=y

y = 7

The coordinates are (2,7)

50- 250 is correct i did that one too
