Plz can someone help me show work for these two problems!! 3x + y = 13 2x - y = -1

Alisiya [41]

Answer:

3x +y = 13

Or, x=13-y/3......eqn(i)

Now putting the value of x

2x - y = - 1

Or, 2(13-y/3) - y = - 1

Or, 26 - 2y /3 - y = -1

Or, 26 - 2y - 3y = - 3

Or, 26 - 5y = - 3

Or, - 5y = - 3 - 26

Or,y = - 39/ (- 5)

Or, y = 7.8~

Which equation represents a line that passes through (-2, 4) and has a slope of 2/5

Ulleksa [173]

Answer:

The equation of line is $5(y-4) = 2( x+2)$

$2 x-5 y+24=0$

Step-by-step explanation:

Step 1:-

Given slope is $m = \frac{2}{5}$ and passes through (-2,4)

$y-y_{1}= m(x-x_{1} )$

$y-4 = \frac{2}{5}(x-(-2))$

$5(y-4) = 2( x+2)$

$2 x-5 y+24=0$
