Answer:
x = -25/3
Step-by-step explanation:
To solve for 'x' the given equation 3x + 15x = -150, we can combine like terms and then isolate the variable 'x'.
First, let's simplify the equation by combining the like terms on the left side:
⇒ 3x + 15x = -150
⇒ 18x = -150
Now, to solve for 'x', we need to isolate 'x' by dividing both sides of the equation by the coefficient of 'x', which is 18:
⇒ x = -150 / 18
∴ x = -25/3
Thus, the solution to the equation is x = -25/3.
