Question

five times a a number is equal to three times the the sum of the number and 4. what is the number?
​

Answer 1

Answer:

Let 5 times a be = 5a

Let other no. = 3a + 4

therefore, 5a = 3a + 4

5a - 3a = 4

2a = 4

a = 4 / 2

a = 2

first no. = 5a = 2 × 5 = 10

second no. = 3a + 4 = 2 × 3 + 4 = 10

hence proved that no. A = no. B
