Question

1. If 8x - 4 = 6x - 10, find the value
5x

2. Find the value of x which satisfies the equation:
5(x-7)=7x-5

3. Solve : 6 (x-4) +3 ( x + 7) = 3

4. Solve the equation 2/ 3 (x + 5) = -15% - 3)

​

Answer 1

Answer:

1.8x-4=6x-10

8x-6x=-10+4

2x=-6

x=-6/2

x=-3

2.

5(x-7)=7x-5

5x-35=7x-5

5x-7x=-5+35

-2x=30

x=30/-2

x=-15

3.6(x-4)+(x+7)=3

6x-24+x+7=3

7x-17=3

7x=3+17

7x=20

x20/7
