Question

solve x+y=3.3 and 0.6/3x-2y   = - 1

Answer 1

0.6/2x-3y= -1
so 0.6=3y-2x
so 3y-2x=0.6 or 3y=2x-0.6

again x+y=3.3
     so 3x+3y=9.9
     so 3x+2x-0.6=9.9
    so 5x=9.9+0.6=10.5
    so  x= 2.1
so y= 3.3-2.1=1.2

answer : x=2.1, y=1.2

Answer 2

Answer:

The values are x=1.2 and y=2.1.

Step-by-step explanation:

Given : Equations $x+y=3.3$ and $\frac{0.6}{3x-2y}=-1$

To find : Solve the equations ?

Solution :

Let $x+y=3.3$ ....(1)

$\frac{0.6}{3x-2y}=-1$

$0.6=-3x+2y$

$-3x+2y=0.6$ ....(2)

Solving (1) and (2),

Multiply (1) by 3 and add in (2),

$3x+3y-3x+2y=9.9+0.6$

$5y=10.5$

$y=\frac{10.5}{5}$

$y=2.1$

Substitute in equation (1),

$x+2.1=3.3$

$x=3.3-2.1$

$x=1.2$

Therefore, The values are x=1.2 and y=2.1.
