Answer:

x= -2

Explanation:

9(x-1)=7x-13 1) do distributive property

9x-9=7x-13 2) add nine to both sides which means you would take out the 9 since -9 and 9 cancel out each other and add 9 to -13

9x=7x-4 3) subtract 7x from both sides which means you would remove the 7x since -7x and 7x cancel out each other and subtract 7x from 9x

2x=-4 4) divide both sides by 2

x= -2

Sorry if this was confusing
