Answer 2

Answer:

Answer is -38

Step-by-step explanation:

Given seven times some number added to 4 amounts,

-20 added to the product of 3 and the number.

Equate from the question.

Let’s assume some number as x,

So,

7x+4=3x-20--------------Equation A

Move 3x to the left and the sign changed we get -3x.

7x-3x +4=-20

Simplify the equation,

4x+4=-20

move 4 to the right and the sign changed.

4x=-24

From the above equation we need to find the value of x,

So x=-24/4,

Divide -24/4 to isolate variable "x".

x=-6  

Substitute the value of x into the equation A.

7(-6)+4=3(-6)-20

-38=-38.
