Question

3×+5 =17 slove the following equations by trial and error method .

Answer 1

Answer:

the value of x is 4.

Step-by-step explanation:

For 1, 3x + 5 = 17 = 3 + 5 = 8 ≠ 17

For 2, 3x + 5 = 17 = 6 + 5 = 11 ≠ 17

For 3, 3x + 5 = 17 = 9 + 5 = 14 ≠ 17

For 4, 3x + 5 = 17 = 12 + 5 = 17 = 17

Only x=4 satisfies the equation.
