How do you solve the system #y= 1.2x - 46# and #y = 0.6x - 0.22# by substitution?
Choose one equation to solve for one of the variables in terms of the other variable (your choice). Substitute the solution you get into the other equation.
I choose to solve the first equation for
Now replace any
Finally, finish by finding
We already "solved" the first equation for
So in the solution,
The solution is:
