Answer:
The required number is 63
Step-by-step explanation :
Let the number be x
Now As per question , the equation is written as
x - 23 = 2 × [ 15 - ( - 3) ] + 4
Or, x - 23 = 2 × ( 18) + 4
Or , x - 23 = 36 +4
Or, x - 23 = 40
So, x = 40 + 23
∴ x = 63
Hence the required number is 63 Answer
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
