1 Solve these simultaneous equations using the elimination method

4x + y = 23
x + y = 8​

y= 3, x= 5

Step-by-step explanation:

4x+y=23

-x-y=-8

3x/3=15/3

x=5

for y

x+y=8

5+y=8

y=8-5

y=3

x=5

y=3

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

its adding 5.5 each time
