How do you solve the following system: #7y - 2x = 10, -5x − y = 14 #?
Let's solve the second equation for y, which should be simply since it doesn't have a coefficient. It starts off as:
Add y to both sides and subtract 14 from both sides:
Now we can plug that into the second equation:
Multiply through: (tip:
Now plug that back into the initial equation:
