If we first convert it to a fraction, we get 490/100. Now if we actually do 490 ÷ 100, we get 4.9, which is the answer. I hope this helps!
Answer:
x=3 and y=1
Step-by-step explanation:
subtract equation 2 from 1
then (2x+3y) -(2x+y) =9-7
2x-2x+3y-y =2
2y=2 therefore y=1
substitute y value in 2x+y=7
2x+1=7
2x=7-1
2x=6
x=3
