The total of two numbers is 28. Four times the smaller number is 7 more than three times the larger number.
navik [9.2K]
Let's define:
x \ \textless \ y

So, you can set up a system of equations:
x + y = 28
4x = 7 + 3y

Now, to solve for both of those values, solve the system of equations:
x = 28 - y
4(28-y) = 7+3y
122-4y=7+3y
115 -4y = 3y
115 = 7y
y = 16.43

Now, plug that y-value into the first equation to solve for x:
x + 16.43=28
x = 11.57

Now, we have both the values. The smaller value (x) = 11.57 and the bigger value (y) = 16.43.
