-3(x-4) + 7 = 4x - 9
Help me please!!

x=4

Step-by-step explanation:

Do your distribution rules to get -3x+12+7=4x-9. Then combine like variables to get -3x+19=4x-9. Add the 9 to 19 and get 28 then add the 3 to 4 to get 7. Should look like 28=7x. Divide the 7 to 28 and get the answer of 4

X=4

Step-by-step explanation:

-3(x-4)+7=4x-9

-3x(12)+7=4x-9

+3x         +3x

      12+7=7x-9

         +9   +9

      12+16=7x

          28=7x

          28/7

           4=x

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
