Answer:
Step-by-step explanation:
Given the system of equation:
y = 5x –4 and y = 7x – 3
Since both functions are functions of x with the same output as y, we can equate both as shown:
5x-4 = 7x-3
collect like terms
5x-7x = -3+4
-2x = 1
x = -1/2
Substitute x = -1/2 into any of the equation
y = 5x-4
y = 5(-1/2)-4
y = -5/2 - 4
y = (-5-8)/2
y = 13/2
Since x = -1/2 and y = -13/2, this shows that the system of equation jhas only one solution.
