Question

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have

Answer 1

Answer:

ONE: x = 10

Step-by-step explanation:

3x + 6 = -1 - 3 + 4x

3x + 6 = -4 + 4x       |subtract 6 from both sides

3x = -10 + 4x      |subtract 4x from both sides

-x = -10      |change the signs

x = 10

Answer 2

Answer:

Only one Solution, x=10

Step-by-step explanation:

This solution is due to the fact that on a graph, the line goes straight up, and never intercepts the y-axis, It remains on the 10 of the x-axis and has no fixed y variable, so it is x=10, Don't believe me? Use your calculator on you computer, set it to graph, Copy and paste this equation into the expression input: 3x + 6 = − 1 − 3 + 4x
