-3(x+5)+3=12
-3(x+5)+3=12
-3x - 15 + 3 = 12
-3x - 12 = 12
-3x = 24
x = -8
you have to solve for x.
-3(x+5)+3
distribute.
you'll get...
-3x-15+3=12
combine like terms.
-3x-12=12
solve for x.
add 12 to both sides.
-3x=24
divide both sides by -3
x=-8
plug the-8 back in to x to see if your answer is right.
-3(x+5)+3=12
-3(-8+5)+3=?
-3(-3)+3=?
9+3=?
12=12
thanks
To solve the equation -3(x+5)+3=12, follow these steps:
Step 1: Simplify the equation by applying the distributive property. Multiply -3 by each term inside the parentheses:
-3 * x = -3x
-3 * 5 = -15
The equation simplifies to:
-3x - 15 + 3 = 12
Step 2: Combine like terms. In this case, combine -15 and 3 to get -12:
-3x - 12 = 12
Step 3: Isolate the variable. To do this, you need to get rid of the constant term (-12) on the left side of the equation. To cancel out the -12, you can add 12 to both sides of the equation:
-3x - 12 + 12 = 12 + 12
Simplifying further:
-3x = 24
Step 4: Solve for x. To solve for x, divide both sides of the equation by -3:
(-3x) / -3 = 24 / -3
The equation simplifies to:
x = -8
So, the solution to the equation -3(x+5)+3=12 is x = -8.
