Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
Answer:
Hi You
5(x -8) = 7(x -4)
5x - 40 = 7x - 28
5x - 40 + 40 = 7x - 28 + 40
5x = 7x + 12
5x -7x = 7x - 7x +12
-2x = 12
-2x/-2 = 12/-2
x = -6
Step-by-step explanation:
proving my answer.
5(-6 - 8)
(5×-6)-(5×8)
= -30-40
= -70
7(-6-4)
(7×-6) - (7×4)
-42 - 28
= -70
hope that will help you.
