How do you solve this system of equations: #0.5x + y = 4.5 , y = x + 3#?
To solve this system of equations, you need to use the substitution method because only one of the variables is defined.
First, substitute for y
Then, combine like terms (Ignore the parentheses)
Finally, solve for x
Since you now know what x is, substitute it in the other equation
Now that you know what both of the variables are, substitute for all the variables to check your answer
Since both of the variables work, we can now come to a conclusion about our answer
We can write our answer like this
