Question

How do I find the solution of each system of equations?
y = 2x - 1
y = 3x + 2

Answer 1

x = -3

y = -7

Explanation:

y = 2x - 1

y = 3x + 2

Set the equations equal to each other

2x-1 = 3x+2

Subtract 2x from each side

2x-1-2x = 3x+2-2x

-1 =x+2

Subtract 2 from each side

-1-2 = x+2-2

-3 =x

Now find y

y = 2x-1

y = 2(-3) -1

y = -6-1

y = -7

Answer 2

x = -3, y = -7

Explanation:

You can set the equations equal to each other, so the set becomes:

2x - 1 = 3x + 2

-x = 3

x = -3

y = 2(-3) -1 = -7
