Question

Which of the following values of x make the following functions equal? y =4x+6 and y=5x+3

3
2
4
1

Answer 1

x=3

Explanation:

Answer 2

The value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is;

x = 3

Explanation:

The given functions are;

y = 4·x + 6 and y = 5·x + 3

For the functions to be equal, we have that the y values are equal, therefore;

y = y and 4·x + 6 = 5·x + 3, which gives;

4·x + 6 = 5·x + 3

5·x - 4·x = 6 - 3

∴ x = 3

Therefore, the value of x that makes both functions. y = 4·x + 6 and y = 5·x + 3 equal is x = 3.
