Answer:
Step-by-step explanation:
y = 5x + 4
-5x + y = 4 ----------------------(i)
3x + 2y = 20 --------------------(ii)
Multiply equation (i) by (-2)
(i)* (-2) 10x - 2y = -8
(ii) <u>3x + 2y = 20</u> { Now add this two equations}
13x = 12 { -2y and 2y got eliminated}
x = 12/13
Plug in value of x in (i)
-5*12/13 + y = 4
-60/13 + y = 4
y = 4 + 60/13
Z = -b - a + 1
subtract 1
1z - 1 = -1b - 1a ( 1z is the same as z, same goes for b and a)
add -1b
1b - 1z - 1 = -1a
then we remove -1 by dividing it.
-1b -(-1z) + 1
Answer: -1b -(-1z) + 1 = A
A negative minus a negative is a positive, so the answer might as well be....
-1b + 1z + 1 = A

Answer:
0.0545454545455
Step-by-step explanation:
Parallel lines has equal slopes ii.e. slope of required line is 3.
Required equation is y + 1 = 3(x - 2) => y + 1 = 3x - 6
