-4+7x+4=8 direct vriation
-4 and 4 get cancelled.
Hence 7x =8
solve for x
actually, since there is only one variable, there is no direct variation. If you meant
-4+7x+4 = y
then y = 7x
is a direct variation.
To solve the equation -4 + 7x + 4 = 8, we need to simplify the expression on the left side of the equation by combining like terms.
Starting with the given equation:
-4 + 7x + 4 = 8
Let's combine the constant terms (-4 and 4) on the left side to simplify the equation:
(-4 + 4) + 7x = 8
0 + 7x = 8
7x = 8
Now, to find the value of x, we need to isolate it by dividing both sides of the equation by 7:
(7x)/7 = 8/7
x = 8/7
Therefore, the value of x that satisfies the equation -4 + 7x + 4 = 8 is x = 8/7.
