Question

0.6x+o.5y=5. /0.8x+0.1y=4.4​

Answer 1

Answer:

Easiest method is to multiply both the equations by 10

Step-by-step explanation:

Now,

6x+5y=50-------(1)

8x+1y=44--------(2)

Now ,there are three ways to solve these types of linear equations.

1.Graphing

2.Substitution method

3.elimination method

( There are more ways to solve ,leave them for now)

Applying Substitution method

6x+5y=50-----(1)

8x+1y=44-------(2)

From equation (2), we get

y=44-8x

Now put this value of y from equation (2) in equation (1)

we get:

6x+5(44-8x)=50

6x+220-40x=50

220-50=40x-6x

170=34x

x= 170/34=5

Now,put x=5 in equation (2), to get y

y=44-8(5)

y=44-40

so x=5 and y = 4

Applying Elimination method

6x+5y=50-----(1)

8x+1y=44------(2)

Multiply equation (2) by 5,so as to make both coefficient of "y"equal

Now equation (2)

(2) 40x+5y=220

(1) 6x+5y=50

Subtracting (2) by (1), we get

40x-6x+5y-5y=220-50

34x=170

x=5

put x = 5 in equation (2)

y=4

So , x=5,y=4
