6 0

Answer: x = - 8

Step-by-step explanation:

\frac{x}{7+x} = 8

cross multiplying , we have

8 ( 7 + x) = x

Expanding the Left  Hand Side of the equation , we have :

56 + 8x = x collecting the like terms , we have

56 = x - 8x

56 = -7x

dividing through by - 7 we have :

- 8 = x  

Therefore :

x = -8

Solve the equation for x, 3(2x-5) - 3(x - 7) = 2x - 9​
AVprozaik [17]

Answer:

x = -15

Step-by-step explanation:

Step 1: Write equation

3(2x - 5) - 3(x - 7) = 2x - 9

Step 2: Distribute

6x - 15 - 3x + 21 = 2x - 9

Step 3: Combine like terms

3x + 6 = 2x - 9

Step 4: Subtract 2x on both sides

x + 6 = -9

Step 5: Subtract 6 on both sides

x = -15
