12х+20-6х=2
12х-6х=2-20
6х=-18
Х=-18:6
Х=-3

Answer 2

To solve the equation 12X - 5 = 7X + 10 + 4(3X + 5) - 6X = 2, we will follow the order of operations (PEMDAS/BODMAS) and simplify the equation step by step.

Step 1: Simplify the equation

Let's start by simplifying the equation by distributing the 4 to the terms inside the parentheses: 12X - 5 = 7X + 10 + 4 * 3X + 4 * 5 - 6X = 2

Simplifying further, we have: 12X - 5 = 7X + 10 + 12X + 20 - 6X = 2

Step 2: Combine like terms

Next, we combine like terms on both sides of the equation: 12X - 5 = 7X + 12X - 6X + 10 + 20 = 2

Simplifying further, we have: 12X - 5 = 13X + 30 = 2

Step 3: Isolate the variable

To isolate the variable X, we need to move all the terms with X to one side of the equation and the constant terms to the other side. Let's subtract 13X from both sides and add 5 to both sides: 12X - 13X = 2 - 30 + 5

Simplifying further, we have: -X = -23

Step 4: Solve for X

To solve for X, we need to multiply both sides of the equation by -1 to get rid of the negative sign: (-1) * (-X) = (-1) * (-23)

Simplifying further, we have: X = 23

Therefore, the solution to the equation 12X - 5 = 7X + 10 + 4(3X + 5) - 6X = 2 is X = 23.
