Answer 1

Answer:

substract 7 from both side.simplfy 4- 4-7 4-7 to -3.

x+7=4.

x=7-4.

X=3.

Answer 2

Given,

The given equation is :

x+7 = 4

To find,

Solving the given equation. (finding the value of variable x)

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Here, we will use normal algebraic method to solve the given equation. (the produced value of x should satisfy the given equation)

So,

x+7 = 4

or, x = 4-7

or, x = -3

(This cannot be further simplified and that's why this will be considered as the final result. This value of x will also satisfy the given equation.)

Hence, the value of x from the given equation is -3
