Step 2: _ Property to get _
Step 3: _ Property to get _
Step 4: _ Property to get _
Step 2: Commutative Property to rearrange the equation as 12x+15=2x−5
Step 3: Combine like terms to get 10x+15=−5
Step 4: Addition Property of Equality to simplify further as 10x=−20
Step 1: Distributive Property to get 2x - 5 = 12x + 15
Step 2: Commutative Property to rearrange the equation as 12x + 15 = 2x - 5
Step 3: Combine like terms by subtracting 2x from both sides to get 10x + 15 = -5
Step 4: Subtract 15 from both sides to get 10x = -20
Step 1: Distributive Property to get 2x - 5 = 3(4x + 5)
Step 2: Use the Distributive Property to distribute 3 to 4x and 5 on the right side of the equation, resulting in 2x - 5 = 12x + 15.
Step 3: By the Commutative Property, rearrange the equation to get 12x + 15 = 2x - 5.
Step 4: Now, we can solve for x by subtracting 2x from both sides of the equation to create 12x - 2x + 15 = -5.
Step 5: Simplify further by combining like terms to get 10x + 15 = -5.
Step 2: Combine like terms on both sides: -5 = 10x + 15.
Step 3: Subtract 15 from both sides to isolate the variable term: -20 = 10x.
Step 4: Divide both sides by 10 to solve for x: -2 = x.
2x - 5 = 3 * 4x + 3 * 5
Simplifying this gives:
2x - 5 = 12x + 15
Step 2: Use the addition property of equality to move all the x terms to one side of the equation.
2x - 12x - 5 = 12x - 12x + 15
This simplifies to:
-10x - 5 = 15
Step 3: Use the addition property of equality to move the constant term (-5) to the other side of the equation.
-10x - 5 + 5 = 15 + 5
This simplifies to:
-10x = 20
Step 4: Finally, divide both sides of the equation by -10 to solve for x.
-10x / -10 = 20 / -10
This simplifies to:
x = -2
So the order of steps is:
Step 1: Use the distributive property
Step 2: Use the addition property of equality
Step 3: Use the addition property of equality again
Step 4: Divide both sides by -10
