Question

solve for asy
0.4x + 0.3y = 1.7
0.7x 0.2y = 0.8​

Answer 1

Answer:

0.3y=17/10-4/13

0.3y=18/13

y=18/13×10/3

y=60/13

Therefore x=10/13 and y=60/13

Answer 2

Step-by-step explanation:

multiply both side by 7 and 4 to make equation easier

then equation is

2.8x+2.1y =1.19

2.8x+.8y=3.2

on equating que

y=2.01/1.3
