To solve for y, we can start by isolating the term with the variable y on one side of the equation. Let's do that:
6x = 7 - 4y
Subtract 7 from both sides:
6x - 7 = -4y
Now, divide both sides by -4, to solve for y:
(6x - 7)/(-4) = y
Simplifying the right side:
y = (7 - 6x)/4
To find the value of y when x = -2, substitute -2 for x in the equation:
y = (7 - 6(-2))/4
Simplifying:
y = (7 + 12)/4
y = 19/4
So, the value of y when x = -2 is 19/4.
The correct answer is C. 19/4.
Solve for y, then find the value of y when given x = –2.
6x = 7 – 4y
A. -12
B. 7/4
C. 19/4
