Answer 1

Answer:

I will solve first three equations, 4th equation you can try himself.

Step-by-step explanation:

1. 5x-7=48

5x=48+7

5x=55

x=55/5

x=11

2. 8x+17=9

8x= 17-9

8x= 8

x= 8/8

x=1

3. 3x+13+6x-11

3x+6x+13-11

9x+2

9x=-2

x= -2/9

Answer 2

Answer:

1. x = 11

2. x = -1

3. 9x - 2

4. x + 46/15

Step-by-step explanation:

1. 5x - 7 = 48

5x = 48 + 7    (Take 7 at the RHS and add it with 48)                                                                      

5x = 55

x = 55/5    (Take 5 at the RHS and divide 55 by 5)

x = 11.

2. 8x + 17 = 9

8x = 9 - 17   (Take 17 at the RHS and subtract it from 9)

8x = -8

x = -8/8  (Take 8 at the RHS and divide -8 by 8)

x = 1

3. 3x + 13 + 6x - 11

3x + 6x + 13 - 11 (First, combine the like terms and then add them)

9x - 2

4. 5x + 2/3 - 4x - 3/5 + 3

5x - 4x - 3/5 + 2/3 + 3 (First, combine the like terms and then do the operations)

x -9/15 + 10/15 + 45/15 (Then, make the denominators equal by LCM of the rational numbers and add.)

x + 1/15 + 45/15

x + 46/15 (or 15x/15 + 46/15 if you make the denominators equal by the LCM method.
