What is the solution to the system of equations y = 3x + 7 and y = x + 9?
To solve the system of equations y = 3x + 7 and y = x + 9, we will set the two equations equal to each other since both are equal to y. Thus, we can write: 3x + 7 = x + 9 Next, we’ll isolate the variable x. Start by subtracting x from … Read more
