The sum of two numbers is 69. The second is 9 more than 4 times the first. What are the two numbers?
would the equation i have be right
4x+y+9=69
4*15+0+9=69
60+9=69
No. Let the two numbers be x and y, with x the smaller number.
x + y = 69
y = 4x + 9
5x + 9 = 69
x = 12
Use any equation with x and y to solve for y.
