The answer is either b or c
(c) 5p + 7 = 12 - 3p
8p = 5
p = 5/8 = 0.625
5. (a)
7p + 2 = 5p + 8
2p = 6
p = 3
(b) 7r + 2 = 5r - 20
2r = -22
r = -11
Answer:
x= -(6/5)
Step-by-step explanation:
if what ur saying = 0
7x+14-2(x+4)
distribute the -2
7x+14-2x-8
7x-2x
14-8
5x+6=0
-6 -6
5x=-6
/5 /5
x= -(6/5)

Answer:</h3>
y = 8/9x + 80/9
<h3>
Step-by-step explanation:</h3>
<u>We are given;</u>
- Equation of a line as 8x -9y -2 = 0
- Coordinates (-1,8)
We are required to determine the equation of a line parallel to the given line and passing through a point (-1,8)
<h3>Step 1: Determine the Gradient of the given line </h3>
- When an equation is written in the form y = mx + c, m is the gradient.
- Therefore; we could write the equation 8x -9y -2 = 0 in the form of y= mx + c
9y = 8x -2
y = 8/9x - 2/9
Therefore, the slope, m = 8/9
<h3>Step 2: Determine the equation of the line</h3>
- We need to know that parallel lines have the same gradient
- Therefore, the slope of the line in question is 8/9
- It passes through a point (-1, 8)
We can therefore, determine the equation;
Taking another point, (x,y)

9(y-8) = 8(x+1)
9y - 72 = 8x + 8
9y = 8x + 8 +72
9y = 8x + 80
y = 8/9x + 80/9
Therefore, the equation of the line is y = 8/9x + 80/9
