Question

which equation has the solution x equals 2. A. 2x-3=19,B 3x+2=8,C 4x-4= -4,D 5x+1=10

Answer 1

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
