Question

Study the equation below 25= 2x + 3

Answer 1

Let's solve 'em all!

Original Equation: 
25 = 2x + 3
-3           -3
22 = 2x
/2    /2
11 = x (So now we are looking for an equation that has the solution: 11) 

A. 
28 = 2x
/2     /2
14 = x

B
22 = 2x
/2    /2
11 = x

C
50 = x + 3
-3         -3
47 = x 

D
25/2 = x + 3
12.5 = x + 3
-3           -3
9.5 = x


Thus, the answer is B since both 25 = 2x + 3 and 22 = 2x both are equivalent to 11.
