Answer:
x = 1.5
Step-by-step explanation:
First, calculate 6-9, which is -3.
Then we add 9 on both sides so that on the left, we only have 4x, and on the right, we have 6.
Then divide by 4 on both sides to get x = 1.5

Answer:
-15/4
Step-by-step explanation:
slope = change in y / change in x = (-7 - 8) / (7 - 3) = -15/4
For this case we must solve the following linear equation:

Adding similar terms from the left side of the equation:

Subtracting
from both sides of the equation we have:

Thus, equality is not fulfilled. So the equation has no solution.
Answer:
No solution
