Solve the system of equations below 4x+y=16 and 2x+3y=-2

2 answers:

7 0

4x+y=16 multiply both sides by -3 and will get
2x+3y=-2

-12x -3y = -48
2x +3y = -2
--------------------------
-10x 0 = -50

-10x = -50

x = -50/(-10) = 5

x = 5

4x+y=16
4*5+y=16
20+y=16

y = 16-20

y = -4

x = 5
y = - 4

HELP PLS GIVING BRAINLIEST

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

$y = mx+b$

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We need two points through which the line passes to find the slope:

$(0,1)\\(1, -2)$

We found the slope:

$m = \frac {y2-y1} {x2-x1}\\m = \frac {-2-1} {1-0} = \frac {-3} {1} = - 3$

So, the equation is of the form:

$y = -3x + b$

We substitute a point to find "b":

$1 = -3 (0) + b\\1 = b$

Finally, the equation is:

$y = -3x+1$
