Question

solve by elimination or substitution:
0.1x+3.2y=2
2x+64y=20

Answer 1

This means that you can either use:
.1x+3.2y=2
2x+64y=20

-2x-64y=-40 { *(-20)
2x+64y=20

0 = -20 => false

Or:

.1x+3.2y=2
2x+64y=20 <=> x=10-32y

.1*(10-32y)+3.2y=2
1-3.2y+3.2y=2
1=2 => false

Answer 2

so there is no solution for this question?

Answer 3

Yes. There are no possible real values for x and y.

Answer 4

which means that the 2 lines that are given are parallel to each other, so they will not intersect at any point.

Answer 5

thank you! brilliant.
