Question

y + 3 = 2x. y + 4 = 3x. If you use the comparison method to solve the given system, what is the resulting equation?. A] y + 3 = y + 4. B] 2x - 3 = 3x - 4. C] 2x + 3 = 3x + 5

Answer 1

y+3 = 2x
y = 2x-3 

y+4 = 3x
y = 3x-4

therefore, 2x-3 = 3x-4
answer is B

Answer 2

y=2x-3 by arranging 
and y= 3x-4 
so it shows that y= 2x-3 and 3x-4 so these both values are same we supposed because both are equal to y. so option b is correct
