What is the answer <br> y=2x+3<br> y=3x+5

Marizza181 [45]

We can use substitution.

We can substitute 2x + 3 for 'y' in the 2nd equation.

y = 3x + 5

2x + 3 = 3x + 5

Subtract 3 to both sides:

2x = 3x + 2

Subtract 3x to both sides:

-x = 2

Multiply -1 to both sides:

x = -2

Now we can plug this into any of the two equations to get our y-value:

y = 2x + 3

y = 2(-2) + 3

y = -4 + 3

y = -1

So our solution is (-2, -1)
