X=√ x = √(15 - 2 * ) 15-2x

Question

X=√

`x = √(15 - 2 * )`
15-2x

Answer 1

The answer: " x = 5 " .
____________________________________
Step-by-step explanation:
____________________________________
Given: " x = √(15 − 2x) " ; Solve for "x" ;
____________________________________
"Square" each side of the equation:
____________________________________
→ (x)² = [√(15 − 2x) ] ² ;

→ x = 15 − 2x ;

Now, add "2x" to each side of the equation:

→ x + 2x = 15 − 2x + 2x ;

→ 3x = 15 ;

Now, divide each side of the equation by "3" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 3x / 3 = 15 / 3 ;

→ " x = 5 " .
