There are two numbers such that the sum of the first and three times the second is 53, while difference between 4 times the first and twice the second is 2. What is the first number?
There are two numbers such that the sum of the first and three times the second is 53, while difference between 4 times the first and twice the second is 2. What is the first number?
Explanation
Given the equations:
x + 3y = 53 ... (1)
4x - 2y = 2 ... (2)
We can solve these equations using substitution or elimination. Let's use elimination.
Multiplying equation (1) by 2 and equation (2) by 3 to eliminate y:
2x + 6y = 106
12x - 6y = 6
Adding both equations:
14x = 112
x = 8
