Question

5 subtracted from two times a number gives 45​

Answer 1

Step-by-step explanation:

To find two numbers such that three times the first added to the second gives 23 , and that five times the first added to three times the second gives 45 . Here we find two ... Five times the first unknown number increased by three times the second , is equivalent to 45 . ... Let x = the greater , and y = the less ; then x + y = s , and e -- y = d ; whence , by addition , 2x = 8 + d , and by subtraction , 2y = 8 - d .

Answer 2

Answer:

number = 25

Step-by-step explanation:

5 substracted two times a number gives 45

=> 2×(number) - 5 = 45

[let us consider number as x]

=> 2×x - 5 = 45

=> 2×x = 45+5

=> 2x = 50

=> x = 50÷2

=> x = 25

Hence the number = 25.
