Given:
The result of the first problem should be 79 and the next problem is 25.
To find:
Frame two linear equations and solve to get the given result.
Solution:
From given, we have,
The result of the first problem should be 79 and the next problem is 25.
Given the linear system
ax + by = m
cx + dy = n
where a, b, c, d, m, and n are real constants, a pair of numbers x = x0 and y = y0 also written as (x0, y0) is a solution to this system if each equation is satisfied by the pair.
The set of all such ordered pairs is called the solution set for the system.
Let us consider, the system of equations to be,
2x + y = 79
2y - x = 25
upon solving these, we get,
x = 133/5 and y = 129/5
We can verify the results by resubstituting the values of x and y in the equations.
