-7-2x=7(x+8) What is the answer for this expression

1 answer:

7 0

Answer:

x=-7

Step-by-step explanation:

1. Distribute the 7 into the parenthesis: -7-2x=7x+56

2. Combine like terms by doing the opposite operation to the numbers: -7=9x+56 (added 2x to 7x)

3. Subtract 56 to each side of the equation: -63=9x

4. To isolate the variable "x," divide each side by 9: x=-7

Answer:

32+9C/5

Step-by-step explanation:

First you must follow PEMDAS, the order of operations. So you mutiply 9 by both sides to get 9C =5(F - 32) then you must divide by 5, to get

9C/5=F-32 and lastly you must add 32 to both sides to cancel out the 32 leaving you with 32+ 9C/5
