You can put this solution on YOUR website! The given system of equations are:
10x - 5y = 17
y = 2x - 3
The solution by substitution is as follows: The given set of equations can be written as:
10x - 5y = 17 ---------------(1)
y = 2x - 3 ---------------(2)
Substitute Equation (2) in equation (1), and we get:
10x - 5(2x - 3) = 17
10x - 10x + 15 = 17
0 + 15 = 17
Thsi implies that right hand side is not equal to left hand side.
Hence, the given system of equations has no solutions.
Hence, the solution.
