Answer:
a= -5 ans
Step-by-step explanation:
2(0)+0-a=5
0-a=5
a=-5
Given:
The equation:-
The value of x:-
What To Find:
We have to find the value of a where x = 0.
Solution:
2x + x - a = 5
Substitute the value of x,
⇒ 2 × 0 + 0 - a = 5
Multiply 2 by 0,
⇒ 0 + 0 - a = 5
Add 0 and 0,
⇒ 0 - a = 5
Omit the zero,
⇒ -a = 5
-a can be written as -1a,
⇒ -1a = 5
Take -1 to RHS,
⇒ [tex]\sf{a = - \dfrac{5}{1}}[/tex]
-5 by 1 can be written as -5,
⇒ a = -5
∴ Hence the value of a is -5.
Verification:
2x + x - a = 5
Substitute the value of x and a,
⇒ 2 × 0 + 0 - (-5) = 5
Multiply 2 by 0,
⇒ 0 + 0 - (-5) = 5
Add 0 and 0,
⇒ 0 - (-5) = 5
Subtract -5 from 0,
⇒ 5 = 5
∴ LHS = RHS
∴ Hence, verified.
