Question

0.2x+0.3y=1
0.4x+0.5y=2
pairs of linear equation by substitution method​

Answer 1

Answer:

x = 5, y = 0

Step-by-step explanation:

in equation 1

x = (1 - 0.3y)/0.2

put this value in equation 2 and you will get

0.4 (1-0.3y)/0.2 + 0.5y = 2

y = 0

put y = 0 in equation 1 you will get

x = 5
