The sum of two numbers is 10. The larger number is 4
times the smaller number. What are the two numbers?
Original system: x + y = 10,
Use the work shown to complete the statement.
The slopes and y-intercepts of the two equations are
y, so this system has
y = 4x
Slope-intercept form:
y = -x + 10,
y = 4x
