Answer:
x = -4
Step-by-step explanation:
Given: -2(4x + 4) - 3x - 2 = 34
To solve this equation, we have to isolate the variable. (Get x by itself).
We'll follow the PEMDAS rule as far as parentheses.
So, -2(4x + 4) - 3x - 2 = 34
= -8x - 8 - 3x - 2 = 34
Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.
Hence:
-8x - 8 - 3x - 2 = 34
+8 +2 +8 +2
-8x - 3x = 34 + 8 + 2
Now, we'll simplify.
-11x = 44
Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.
-11x = 44

x = -4
Answer: y - 5 = -5/6 (x - 18)
Step-by-step explanation:
The point-slope form of a linear equation is written using the slope of the line and one point in the line. From part A, the slope of the line representing this situation is m = -5/6.
Since x represents the number of 10-student groups and y represents the number of 12-student groups, the combination of 18 groups of 10 students and 5 groups of 12 students is represented by the point (18,5).
An infinite number of solutions means a coincident line...it is the same line
3y = 2x - 9...divide by 3
y = 2/3x - 3...hmm...same line as answer choice b....they are coincident lines and have infinite solutions
