Which equation has the solution x equals 2. a. 2x-3=19,b 3x+2=8,c 4x-4= -4,d 5x+1=10

Can either solve for x for all of the options or plug 2 in fro x for all of them (easier):
A)2x-3=19
4-3=19  
 1=19           (not A, 1 doesnt equal 19)
B) 3x+2=8
6+2=8
8=8              (8 does equal 8)

B is the answer

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
