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! :)
