Identity property. Anything multiplied by 1 will give an answer identical to the operand.
The idea is to use the addition/subtraction property. In other words, take the derivative of 5x, take the derivative of 1, and subtract the results.
The equation is true because of the reflexive property of equality which states in words that every quantity is equal to inself.

-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
1. Write equation on paper. 2. Use Distributive Property. 3. Combine like terms. 4. Use reflexive Property. (ex.- adding or subtracting 3x to both sides) 5. Inverses Property of Addition ( answer; almost to final answer) 6. Reflexive Property. (ex.- add or subtract 2 to both sides of equation) 7. Inverse Property of Addition (ex.- 5x=5) 8. Multiplication Property (ex. 5x/5= x=1 OR (1/5)(5x) = 1/5(5)= x=1 9. Final answer (ex: x=1)

The equation is true because of the reflexive property of equality which states in words that every quantity is equal to inself.
5x-1+2= 5x+1
5x - 1 = 24 5x - 1 + 1 = 24 + 1 5x = 25 5x/5 = 25/5 x = 5
