How do you solve #x = -5 + 2y# and #2x + 3y = 4# using substitution?
To solve, substitute the
The first equation is already solved for
Next, use the distributive property to simplify our equation:
Now, let's combine
The final step in solving for y is to divide each side by
We've now solved for y. Now, we have to solve for x. The easiest way to do this is to substitute our y-value into the first equation, since it's already solved for x:
Using our x and y value and combining them to get an ordered pair, we now have our answer:
