Question

Solve these equations:

y= -2x-4

y= 3x+1​

Answer 1

(-1, -2)

x = -1 y = -2

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

Answer 2

For the first one x=-2
For the second one x= -1/3
