Answer:
x=-2
Step-by-step explanation:
6(x + 1) = -2(3x + 9)
Distribute 6 and -2.
6x+6=-6x-18
Move the variable to the left-hand side and move the constant to the right and change their signs.
6x+6x=-18-6
Collect like terms.
12x=-24
Divide both sides of the equation by 12.
x=-2
Hope this helps :)
The error is 65 and it need to be added by 60 so the answer is -5
Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Multiply by -1 both sides ( remember that the sign of the inequality change)

The solution is the interval ----> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of x=-4 (close circle)
