Question

What value correctly fills in the blank so that the expressions are equivalent?

18+45 = x (2+5)
A 2
B O3
C 07
D 9

Answer 1

D) 9

Explanation:

Given :

⇒ 18 + 45 = x (2 + 5)

=============================================================

Simplify both sides :

⇒ 18 + 45 = x (2 + 5)

⇒ 63 = 7x

⇒ 7x = 63

=============================================================

Divide both sides by 7 :

⇒ 7x/7 = 63/7

⇒ x = 9

Answer 2

D, x = 9

Explanation:

`x\left(2+5\right)=63`

=> divide both side by 7

`(x\left(2+5\right))/(7)=(63)/(7)`

x=9
