Answer:
x <5
Step-by-step explanation:
2(4 x + 3) < 5 x + 21
Distribute
8x +6 < 5x +21
Subtract 5x from each side
8x -5x +6 < 5x-5x+21
3x +6 < 21
Subtract 6 from each side
3x+6-6 <21-6
3x <15
Divide each side by 3
3x/3 <15/3
x <5

Answer:
Value of x is, 8
Step-by-step explanation:
Given:
,.....[1]
To find the value of x:
Using exponent rules:
Taking square both sides in [1] we have;

Simplify:

or

Multiply both sides by
we get;

Simplify:

or

Simplify:
x = 8
Therefore, the value of x is, 8
