Answer 1

Answer:

when x is 0 then 0+3 is 3

x=1. 1+3 = 4

x=2. 2+3 =5

x=3. 3+3 =6

x=4. 4+3=7

x=5. 5+3=8

Answer 2

Given : -

Solve the equation by trial and error method.

x + 3 = 7

Step-by-step Explanation : -

L.H.S⠀⠀⠀⠀R.H.S

x + 3 ⠀⠀⠀⠀⠀7

Now : -

Value 1 (Using x = 1) : -

x + 3 = 7

1 + 3 = 7

4 ≠ 7 is not a solution.

Value 2 (Using x = 2) : -

x + 3 = 7

2 + 3 = 7

5 ≠ 7 is not a solution.

Value 3 (Using x = 3) : -

x + 3 = 7

3 + 3 = 7

6 ≠ 7 is not a solution.

Value 4 (Using x = 4) : -

x + 3 = 7

4 + 3 = 7

7 = 7 is a solution.

L.H.S = R.H.S

Value 5 (Using x = 5) : -

x + 3 = 7

5 + 3 = 7

8 ≠ 7
