= 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>
Answer:
The 2 numbers are 22 and 23
Step-by-step explanation:
let the two numbers be x and x+1
according to the question:
(x+1)^2 - x^2 = 45
x^2+1+2x - x^2 = 45
2x + 1 = 45
2x= 44
x = 22
the other number is x+1 = 22+1 = 23
therefore, the two consecutive numbers are 22 and 23
