Question

1.5x + 0.1y = 6.2 :;
3x - 0.4y = 11.2

plz send me the pics of the answer​

Answer 1

Answer:

x=4 and y = 2

Step-by-step explanation:

1.5x + 0.1 y = 6.2

10(1.5x + 0.1 y)=10×6.2

15x+y = 62 ________( 1 )

3x-0.4y=11.2

10(3x-0.4y) = 10(11.2)

30x - 4y = 112 ____________(2)

Multiplying equation (1) by 4.

4(15x+y = 62 )

60x + 4y = 248 _________(3)

Adding Equ. (2) and (3).

60x + 4y + 30x - 4y= 248 +112

90x = 360

x = 4

Put x in Equ.(1)

60 × 4+ 4y = 248

240 + 4y = 248

4y = 8

y = 2

therefore ,

• x = 4 and y = 2
