Solve the linear equation: x+x+2+x+4+x+6=-28. State the property that justifies your first step and why you chose it.
When I solved the equation I got the answer of
×=-10. However, I do not know what the property I need to state for my first step. Isn't it subtraction property of equality?
How do I state which property of exponents justifies each step of this simplification?: 3^2x^6z^10/2^2y^18*x^4y^4z^4/5z^3*27z^6/2^2x^2y^3 Im really stuck on this problem, I've managed to figure out the first 5 problems but this
So what I have to do is say which property justifies each step, this is what I put and my teacher said I got it wrong... could someone please help me? question~ 3. (6a + 2a) +8b = (6 + 2)a + 8b Answer~ Associative property of
State the property that justifies the statement: If 3x = 6, then x = 2. A. Subtraction Property of Equality B. Addition Property of Equality C. Division Property of Equality D. Multiplication Property of Equality*** Can you please
1. Name the property that Justifies each step in the simplification below. 1/2[(x+2)+(-x)]=1/2[-x+(x+2)] a.__?__ =1 /2[(-x=x)+2)] b.__?__ = 1/2(0+2) c.__?__ = 1/2*2 d.__?__ =1 e.__?__ My answers a. Communitive Property
solve each of the following systems by substitution. 16) 5x -2y = -5 y - 5x = 3 20) 8x -4y = 16 y = 2x - 4 28) 4x -12y = 5 -x + 3y = -1 Step one: Solve on of the equations for one of the variables. y=2x-4 Step two:Substitute the
