-2(3x-15)-4 = 56
Let's simplify the equation step by step:
Start with -2(3x - 15):
-2 * 3x = -6x
-2 * -15 = 30
So, -2(3x - 15) becomes -6x + 30.
Now, substitute this into the equation:
-6x + 30 - 4 = 56
Combine like terms:
-6x + 26 = 56
Now, isolate the variable by subtracting 26 from both sides:
-6x = 56 - 26
-6x = 30
Finally, divide both sides by -6 to solve for x:
x = 30 / -6
x = -5
Thus, the solution to the equation -2(3x-15)-4 = 56 is x = -5.
Let's solve the given equation step-by-step.
Step 1: Simplify the equation:
Start by applying the distributive property by multiplying -2 with each term inside the parenthesis:
-2 * 3x = -6x
-2 * (-15) = 30
The equation becomes:
-6x + 30 - 4 = 56
Step 2: Combine like terms:
Combine the constant terms on the left side of the equation:
-6x + 26 = 56
Step 3: Isolate the variable term:
Isolate the variable term by subtracting 26 from both sides of the equation:
-6x + 26 - 26 = 56 - 26
-6x = 30
Step 4: Solve for x:
Divide both sides of the equation by -6 to solve for x:
-6x / -6 = 30 / -6
x = -5
Therefore, the solution to the given equation is x = -5.
To solve the given equation, let's go through the steps:
1. First, distribute the -2 to the terms inside the parentheses:
-2 * 3x = -6x
-2 * -15 = 30
The equation becomes:
-6x + 30 - 4 = 56
2. Next, combine like terms:
-6x + 26 = 56
3. To isolate the variable, subtract 26 from both sides of the equation:
-6x + 26 - 26 = 56 - 26
-6x = 30
4. Finally, divide both sides of the equation by -6 to solve for x:
x = 30 / -6
x = -5
Therefore, the solution to the equation -2(3x-15)-4 = 56 is x = -5.
