Question

thrice a number minus 5 x 7 is equals to 28 find the number​

Answer 1

Answer:

11

Step-by-step explanation:

In such questions, in any case, our first step should be assuming the required number to be a variable which may be a, b, c, x, y, z, etc.

Let the required number be 'x'.

Now, on reading the question carefully we can easily form the following equation,

3x - 5 = 28

3x = 28 + 5

x = 33/3

x = 11

Hence, the required number is 11.

Answer 2

Step-by-step explanation:

Answer :21

First we have to consider the following number as x

Therefore our equation will be 3x-5×7=28

then,

3x-35=28

3x=28+35

3x=63

x=63/3

x=21
