Question

solve the system any algebraic method.
3.3x-1.5y=5.22
1.1x+2.6=7.32

Answer 1

y = (5.22 - 3.3x)/1.5
y = (7.32-1.1x)/2.6

Set y = y
(5.22 - 3.3x)/1.5 = (7.32-1.1x)/2.6

Cross Multiply:
13.572-8.58x = 10.98 - 1.65x

6.93x = 2.592

x = 0.374026

Answer 2

y = 2.66

Answer 3

that works
you could also multiply by 100 to get rid of decimals

Answer 4

Yeah, I didn't think to do that

Answer 5

For some reason, I just like using the original numbers

Answer 6

Either way, you end up with a decimal answer
