x = - 2
Step-by-step 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
