Answer:

x = -1 , y = 1

Step-by-step explanation:

Solve the following system:

{5 x + 3 y = -2 | (equation 1)

3 x + 2 y = -1 | (equation 2)

Subtract 3/5 × (equation 1) from equation 2:

{5 x + 3 y = -2 | (equation 1)

0 x+y/5 = 1/5 | (equation 2)

Multiply equation 2 by 5:

{5 x + 3 y = -2 | (equation 1)

0 x+y = 1 | (equation 2)

Subtract 3 × (equation 2) from equation 1:

{5 x+0 y = -5 | (equation 1)

0 x+y = 1 | (equation 2)

Divide equation 1 by 5:

{x+0 y = -1 | (equation 1)

0 x+y = 1 | (equation 2)

Collect results:

Answer: {x = -1 , y = 1

Solve these equation<br><br>4(3-x)=(1-2x)

serg [7]

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

$:\implies\tt{4(3 - x) = (1 - 2x)}$

$:\implies\tt{(12 - 4x) = (1 - 2x)}$

$:\implies\tt{12 - 4x = 1 - 2x}$

Combining like terms, we get,

$:\implies\tt{12 - 1 = - 2x + 4x}$

$:\implies\tt{11 = 2x}$

$:\implies\tt{2x = 11}$

$:\implies\tt{x = \frac{11}{2} }$

$:\implies\tt{x = 5.5}$

The value of x is 5.5
