Answer 1

$\bf\underline{\underline{\blue{SOLUTION:-}}}$

Question

• Solve by elimination method 0.5x + 0.3y =0.3 and 0.6x + 0.3y = 0 ?

Answer

• x= -3
• y= 6

Given

• 0.5x+0.3y=0.3
• 0.6x+0.3y=0

To Calculate

• Value of x and y

Step by Step Explanation

$\bf\underline{\underline{\red{Elimination\:Method:-}}}$

• 0.5x+0.3y=0.3___________(1)
• 0.6x+0.3y=0____________(2)

Multiply equation 1 and 2 by 10

• 5x +3y=3 _________(3)
• 6x +3y=0 _________(4)

On subtracting eq 3 from 4

6x+3y=0

5x+3y=3

_________

x= -3

_________

Putting value of x in equation 4

6x+3y=0

☛ 6×(-3)+3y=0

☛ -18+3y=0

☛ 3y = 18

☛ y= 18/3

☛ y= 6

$\bf\underline{\underline{\blue{HENCE:-}}}$

• x= -3
• y= 6
