Answer:

Given :0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3

To Find solve using substitution method

Solution :

0.2x + 0.3y = 1.3

0.4x + 0.5y = 2.3 -2

Substitute the value of x from 1 in 2

0.4(1.3-0.3) +0.5y = 2.3

y = 3

0.2x + 0.3(3) = 1.3

0.2x = 1.3 0.9

X = 1.3-0.9 0.2

x = 2

So, x = 2 and y = 3

Answer:

[tex]y=5[/tex]

Step-by-step explanation:

[tex]8-1.2y=2[/tex]

Subtract 8 from both sides.

[tex]-1.2y=2-8[/tex]

Subtract 8 from 2 to get -6.

[tex]-1.2y=-6[/tex]

Divide both sides by -1.2.

y= [tex]\frac{-6}{-1.2}[/tex]

Expand [tex]\frac{-6}{-1.2}[/tex] by multiplying both numerator and the denominator by 10.

[tex]y=\frac{-60}{-12}[/tex]

Divide -60 by -12 to get 5.

[tex]y=5[/tex]

Hope this helps! Brainliest would be much appreciated! Have a great day! :)
