9(x-1)=7x-13 what is x

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
