Question

4. Solve each of the following equations by trial and error method:
(1) X-5-1
(ii) 2x+1-7
(iii) 3x - 1=17
​

Answer 1

Answer:

1 . X=6

2.X=3

3. X=6

Step-by-step explanation:

1. X-5=1

X=5+1

X=6

2. 2X+1=7

2X=7-1

2X=6

X=6/2

X=3

3. 3X -1=17

3X=17+1

3X=18

X=18/3

X=6

Answer 2

Answer:

1. X = 6

2. X = 3

3. X = 6

Step-by-step explanation:

1.

X - 5 = 1

X = 5+ 1  

X = 6

2.

2X + 1 = 7

2X = 7 - 1

2X = 6

X = 6 / 2

X = 3

3.

3X - 1 = 17

3X = 17 + 1

3X = 18

X = 18 / 3

X = 6
