Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.​

Answers

[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]

The values of :

[tex]x = 2[/tex]

[tex]y = 3[/tex]

The given equations are :

[tex]0.4x + 0.3y = 1.7[/tex]

[tex]0.7x - 0.2y = 0.8[/tex]

now, let's multiply both the equations with 10 on both sides.

so, now our equations will be :

[tex]4x + 3y = 17[/tex]

[tex]7x - 2y = 8[/tex]

from Equation second :

[tex]7x - 2y = 8[/tex]

[tex]2y = 7x - 8[/tex]

[tex]y = \dfrac{7x - 8}{2} [/tex]

now, let's substitute the value of y from here into Equation first.

[tex]4x + 3y = 17[/tex]

[tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex]

[tex]4x + \dfrac{21x - 24}{2} = 17[/tex]

[tex] \dfrac{8x + 21x - 24}{2} = 17[/tex]

[tex] \dfrac{ 29x - 24 }{2} = 17[/tex]

[tex]29x - 24 = 34[/tex]

[tex]29x = 34 + 24[/tex]

[tex]29x = 58[/tex]

[tex]x = \dfrac{58}{29} [/tex]

[tex]x = 2[/tex]

here, we got the value of x = 2, let's plug it in equation second to find value of y :

[tex]7x - 2y = 8[/tex]

[tex]7(2) - 2y = 8[/tex]

[tex]14 - 2y = 8[/tex]

[tex]2y = 14 - 8[/tex]

[tex]2y = 6[/tex]

[tex]y = \dfrac{6}{2} [/tex]

[tex]y = 3[/tex]

And value of y = 3

Step-by-step explanation:

[tex]\frac{m}{-\frac{6}{5} }[/tex] , is equivalent to

m ÷ - [tex]\frac{6}{5}[/tex] , substitute given value of m

= 6 [tex]\frac{3}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( change mixed number to improper fraction )

=  [tex]\frac{27}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( leave first fraction, change ÷ to × , flip second fraction )

= [tex]\frac{27}{4}[/tex] × - [tex]\frac{5}{6}[/tex] ( cancel 27 and 6 by 3 )

= [tex]\frac{9}{4}[/tex] × - [tex]\frac{5}{2}[/tex] ( multiply values on numerator/ denominator )

= - [tex]\frac{9(5)}{4(2)}[/tex]

=  - [tex]\frac{45}{8}[/tex]

= - 5 [tex]\frac{5}{8}[/tex]
