X ÷ 4 + 5= 8 I need someone to do it and double check for me please.​
kow [346]

= x/4 + 5 = 8

= x/4 = 8 - 5 ( transposing +5 from LHS to RHS changes +5 to -5 )

= x/4 = 3

= x = 3 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 l

= x = 12

Let us see whether the value of x is correct or not by placing 12 in the place of x .

= 12 ÷ 4 + 5 = 8

= 3 + 5 = 8

= 8 = 8

= LHS = RHS

Which means the value of x we found out is correct .

<h3>Therefore , x = 12 .</h3>
