WebJul 22, 2024 · SnO 2 + H 2 → Sn + 2 H 2 O. This puts the hydrogen atoms out of balance. Now there are two hydrogen atoms on the left and four hydrogen atoms on the right. To get four hydrogen atoms on the right, add a coefficient of 2 for the hydrogen gas. The coefficient is a number that goes in front of a chemical formula. WebIn its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 …

WebAn equation is a statement that two expressions are equal. For example, the expression 5 + 3 5 +3 is equal to the expression 6 + 2 6 +2 (because they both equal 8 8 ), so we can write the following equation: 5 + 3 = 6 + … WebExample 1: Solve 3 + x = 4. Solution: Given, the equation is; 3 + x = 4. We can see, on the Left hand side, the variable x is present. Thus, we need to make the variable ‘x’ alone on LHS. Thus, by subtracting the 3 from LHS and RHS we get; 3 + x – 3 = 4 – 3. x = 1. Hence, the solution is x = 1. kids eat and play restaurants
