Solve the Equation.
6x−3(x+8)=9
x=?
2 answers:
First distribute -3 into the parenthesis. you will get 6x-3x-24=9. Then subtract 6x and 3x because they're like terms. you will get 3x -24=9. After that add 24 by both sides and get 3x=33. this step is easy just divide by both sides and you will get x.
Answer:
x = -5
Step-by-step explanation:
Simplifying
6x + -3(x + -8) = 9
Reorder the terms:
6x + -3(-8 + x) = 9
6x + (-8 * -3 + x * -3) = 9
6x + (24 + -3x) = 9
Reorder the terms:
24 + 6x + -3x = 9
Combine like terms: 6x + -3x = 3x
24 + 3x = 9
Solving
24 + 3x = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-24' to each side of the equation.
24 + -24 + 3x = 9 + -24
Combine like terms: 24 + -24 = 0
0 + 3x = 9 + -24
3x = 9 + -24
Combine like terms: 9 + -24 = -15
3x = -15
Divide each side by '3'.
x = -5

We need to create an equation in order to solve this problem.
Let x = the smallest number
x+1 = next number
x+2 the following number
x+3
x+4
x+5
x+6
So, we add those.
x+x+1+x+2+x+3+x+4+x+5+x+6=105
7x+21=105
7x = 84
x = 12
So the numbers are
12,13,14,15,16,17,18
24-(7+5)/6+8
