6 0

The answer will be 30. Using PEMDAS, or the Order of Operations, you will first do 18÷3, which will equal 6. Then multiply the 6×4, which will be 24, then add the final 6 to equal 30.

5x-15 = 8x-8 what is x?

Reptile [31]

Answer:

-7/3 =x

Step-by-step explanation:

5x-15 = 8x-8

Subtract 5x from each side

5x-5x-15 = 8x-5x-8

-15 = 3x-8

Add 8 to each side

-15+8 = 3x-8+8

-7 = 3x

Divide each side 3

-7/3 = 3x/3

-7/3 =x
