Hi everyone, I wonder if someone could show me how to "check" a problem to make sure I have the right answer? I am trying and it isn't coming out. 38=30-2(x-1). My answer is -3 =x. If anyone can help I'd appreciate it, Denise:) Hope no one was in Texas near the tornados today!!:(

To check your answer, plug your solution of x in for x. So plug -3 in for x and see if both sides of the equation are equal

yes, but I need to prove it's right by writing out my "checking" it? By putting the -3 where the x is?

38=30-2(x-1) 38=30-2(-3-1) 38=30-2(-4) 38=30+2(4) 38=30+8 38=38, your answer is right

So DW, the -2 changes to a plus because it's a multiplication with 2 negatives following?

-2 times -4 is +8

We use order of operation to determine how to do things. Parenthesis first -3-1 is -4 multiplication is next -2 times -4 is 8 addition is last
