Question

10-4=-7x+4

Answer 1

10-4 is 6

So we are given that

-7x + 4 = 6

So

-7x + 4 -4 = 6 -4 [Subtracting 4 from both sides to get rid of the 4 in the LHS]

-7x = 2

-7x/7 = 2/7 [Dive both sides by 7 to get rid of the '7' in the LHS]

-x = 2/7

x = -2/7

Now we divide and subtract both the sides to keep the inequality equal.
And to get the value of x. :D

Understood? :)
