Solve these equations:

y= -2x-4

y= 3x+1

       (-1, -2)

x = -1          y = -2

Step-by-step explanation:

y= -2x-4

y= 3x+1

Substitution:

3x + 1 = -2x - 4

5x + 1 = -4

5x = -5

x = -5 ÷ 5

x = -1

y= 3x+1

y= 3(-1)+1

y = -3 + 1

y = -2

its 4 because 2 times 2 is 4, if you double the number two you get four
