Question

Give any 3 examples for simple equations use in different situations of daily life​

Answer 1

Answer:

Example 1: Prove that LHS = RHS in this equation x + 4 = 10

Solution: x + 4 = 10

x + 4 - 4 = 10 - 4

x = 6

The value of X is 6 and when X is replaced with the value in the equation we get

6 + 4 = 10

Therefore, LHS = RHS

Example 2: In an isosceles triangle, the vertex angle is 40 degrees. What are the base angles of the triangle? (Remember, the sum of three angles of a triangle is 180 degrees)

Solution:

In an isosceles triangle, the base angles are equal.

Let the base angles be of x degrees each.

The Sum of three angles of a triangle is 180

40 + x + x = 180

40 + 2x = 180

Now, transposing 40 will make it -40.

2x = 180 - 40

2x = 140

Now again transposing 2, will make it /2

x = 140/2

x = 70

Thus the base angles are 70 degrees each.

______

For example : Find the value of x

3x - 5 = 10

3x = 10 + 5

3x = 15

x = 15/ 3

x = 5

Therefore, the value of x is 5

For example: 4x + y = 11 with values of x and y being 2 and 3 respectively.

4(2) + 3 = 11

8 + 3 = 11

11 = 11

Therefore, LHS = RHS
