Question

Solve the system using substitution

y = 3x
-2x + y = 2

Answer 1

Start with the first equation:

y = 3x

Now, substitute this expression for y into the second equation:

-2x + (3x) = 2

Combine like terms:

-2x + 3x = 2

Simplify:

x = 2

now we found the value of x, you can use it to find the value of y by plugging it back into the first equation:

y = 3x

y = 3(2)

y = 6

The solution to the system of equations is x = 2 and y = 6.
