Question

Which of the following is the solution to the equation 2x + 3 = 7?

(A) x = 2
(B) x = 3
(C) x = 4
(D) x = 5

Answer 1

Our answer is x = 2.

`\Large\texttt{Explanation}`

We are asked to solve the following equation -

2x + 3 = 7

subtract 3 from both sides -

2x = 7 - 3

2x = 4

divide both sides by 2 -

x = 2

`\therefore` x = 2

Answer 2

2x+3=7
2x=4
x=2

so the answer is (A)
