Answer:</h2>
- option (c) = -19 + x = -21
<h2>Step by step explanation:</h2>
<u>Question</u> : A number added to -19 is -21
<h3>
<u>Solution</u> ↓</h3>
First of all to make equation
Equation means LHS = RHS
For eg we take :-
50 - 20 = 10 + 20
30 = 30
Therefore, LHS = RHS
<h3>
According to the question :</h3>
- Which number would we add in -19 to get -21 and we get LHS = RHS
Make an equation
-19 + x = -21
x = -21 + 19
x = -2
Add -2 in the variable of x
Variable means any unknown value we used in maths. For eg :- x,y,z,a,b,c,p,q,r etc.
-19 + (-2) = -21
-19 - 2 = -21
-21 = -21
Therefore, LHS = RHS.
