Question

Solve for x:
-2 (x+3) = -2 (x+1) -4

A. 2
B. 3
C. all real numbers
D. no solution

Answer 1

first multiply thru to remove the negative signs
2 (x-3) = 2 (x-1) +4
then divide each side by 2
x-3 = x-1+4
move the -3 to the other side by adding 3 to each side
x = x -1+4+3 ... add
x = x +6
can a number equal itself plus 6?
no, so your answer is?
