Answer:
There are no solutions
Step-by-step explanation:
4/5 ( 20x + 5 ) = 16x - 2
Distibute on the left:
( 4/5 x 20 x ) + ( 4/5 x 5 ) = 16x - 2
16x + 4 = 16x - 2
Subtract 16x from both sides:
4=-2
Add 2 to each side:
6=0
No solutions

Answer:
y = 2x + 1 --> linear
y = -4x + 7 --> non-linear
Not a solution for linear system.
Step-by-step explanation:
for (a), y = 2x+1, substitute the x and y values. keep in mind, that in a linear pair, (x, y). So, for the first equation you get:
7 = 2x3 + 1. This is correct, because 6 + 1 is 7. Therefore, (a) is linear.
for (b), we have to substitute our values again. You get:
7 = -4x3 + 7, which is
7 = -12+7, which is not true. So, (b) is not linear.
This means that for the linear pair (3, 7), it does not satisfy both equations, which means that it is not a solution for the linear system.
