Answer:

x=7

Step-by-step explanation:

3(2x - 5) = 9(10 - x)

6x-15=90-9x

6x+9x=90+15

15x=105

x=7

Answer:

x = 7

Step-by-step explanation:

First, we need to expand the brackets:

3(2x-5)=9(10-x) (equation given)

6x-15=90-9x

15x -15 = 90 (add 9x on both sides)

15x = 105 (add 15 on both sides)

x = 7 (divide by 15 on both sides)

Hope this helps :)
