Question

please solve these sums
1) If x + 3 = 7, then x =
2)Solve for x from the equation: 2x + 6 = 11
3)Find the value of x from the equation : 3x - 10 = 11
4)If x - 10 = 14 - 3x then x =
5)If 2x + 11 = 20 + 5x, then x =

Answer 1

1) If x + 3 = 7, then x =

sol-: x+3=7

×=7-3

×= 4..

2.Solve for x from the equation: 2x + 6 = 11

2x+6=11

2×=11-6

2×=5

×=5/2, x= 2.5...

3.Find the value of x from the equation : 3x - 10 = 11

3x-10=11

3×=11+10

x= 21/3 , x= 7 ...

4)If x - 10 = 14 - 3x then x =

x-10=14-3x

x+3x=14+10

x+x= 24/3

2x = 8

x=8/2 , x= 4...

5)If 2x + 11 = 20 + 5x, then x =

2x+11=20+5x

2x- 5x= 20-11

3x= 9

x= 9/3 , x= 3.....
