Question

will you answer and explain this?
$4x + 5 = 25.x =$
​

Answer 1

Answer:

, let's simplify

4

x

+

5

>

25

.

We could subtract

5

from both sides:

4

x

+

5

−

5

>

25

−

5

4

x

>

20

Then divide each side by

4

:

4

x

4

>

20

4

x

>

5

Time to graph! Usually, I'd draw a regular graph first (in this case,

x

=

5

), as if it were an equal sign:

And then, I'd have a look at the simplified inequality. It says

x

>

5

;

x

is more than

5

, so I'd shade the entire area that's more than

5

, which is to the right of the line.

Answer 2

Question :-

» 4x + 5 = 25. Find the value of x.

Answer :-

~ Here we will move 5 to the LHS ( left hand side ) than subtract 5 from 25 and then move the 4 to the divide the number by 4 to get the value of x.

Solving :-

» 4x + 5 = 25

» 4x = 25 - 5

» 4x = 20

» x = 20/4

» x = 5

Therefore, the value of x is 5
