Help!
Solve:
1. 3x + 15 = 0
2. 6x + 18 =0
thanks!
I'll do the first one.
3x + 15 = 0
3x = -15
x = -5
I'll be glad to check your work for the second problem.
2. 6x + 18 =0
6x/6 = 18/6
x = 3??
x = -3
You're on the right track, Good job!
Almost right.
But you forgot to subtract 18 from the right side of the equation.
6x + 18 =0
6x/6 = -18/6
x = -3
To check it, substitute -3 for x.
6(-3) + 18 = 0
-18 + 18 = 0
That's it!
thank you
You're welcome.
To solve the equations, we need to isolate the variable x.
For equation 1: 3x + 15 = 0
1. Start by subtracting 15 from both sides of the equation to isolate the variable:
3x + 15 - 15 = 0 - 15
3x = -15
2. Divide both sides of the equation by 3 to solve for x:
3x/3 = -15/3
x = -5
Therefore, the solution to equation 1 is x = -5.
Now let's solve equation 2: 6x + 18 = 0
1. Start by subtracting 18 from both sides of the equation to isolate the variable:
6x + 18 - 18 = 0 - 18
6x = -18
2. Divide both sides of the equation by 6 to solve for x:
6x/6 = -18/6
x = -3
Therefore, the solution to equation 2 is x = -3.
So, the solutions to the given equations are:
1. x = -5
2. x = -3
