Question

s. Check whether, if x = 3, is a solution of the linear
equation 10x + 7 = 13 - 5x or not.​

Answer 1

Answer:

No x=3 is not a solution

Step-by-step explanation:

When x = 3 ,

10 (3) + 7 = 13 - 5(3)

30 + 7 = 13-15

37 = -2

As we know that 37 is not equal to -2

x=3 is not a solution.

The correct solution is:

10x+7 = 13-5x

15x = 6

x = 6/15 = 2/5 = 0.4

Answer 2

Answer:

Step-by-step explanation:

let's check it by trial and error method

10x + 2 = 13

L.H.S. 10x +2

let's take x = 1

10*1+2

10+2

12

R.H.S. 13

12 is not equal to 13

L.H.S. NOT EQUAL TO R.H.S.

NOT POSSIBLE

LET'S TAKE X=2

L.H.S. 10*2+2

20+2

22

R.H.S. 13

22 IS NOT EQUAL TO 13

L.H.S. IS NOT EQUAL TO R.H.S.

NOT POSSIBLE

hence x=1 and x = 2 is not the solution to the following equation
