So to solve this question the first step should be to make 7 equal to 42. To do this multiply 7 by 6, likewise with x-4.
The new equation should be 42/6x-24 = 42/12.
We now can just get rid of the numerators (top number) to get 6x-24=12.
The next step is to add 24 to both sides which would leave you with 6x=36.
Divide by 6 and the answer should be x=6

Cross multiply
7 * 12 = 42(x - 4)
Expand by using distributive property
84 = 42x - 168
42x = 84 + 168
42x = 252
x = 6

Which equation represents a line that passes through the point (−2, 6) and is parallel to the line whose equation is 3x − 4y = 6

mart [117]

Method 1: Realize that the desired equation will look exactly the same as the given equation 3x − 4y = 6, except that the constant will be different.

Thus, the equation of the new line is 3(-2) − 4(6) = C, where C comes out to 30.

Then the new line is 3x - 4y = 30.
