3m-n=5
2m+5n=7

Answer plz

This is simultaneous equation btw if you want to search up the lesson

3m-n=5
2m+5n=7

multiple the first equation by 5 so it could be equal to the second equation

15m-5n=25
2m+5n=7

the -5n and +5n cancel each other!

so it’s
15m=25
2m=7
(add the equations together)

17m=32
m=1.8

now take an equation from above (the original ones)
3m-n=5

3x1.8-n=5

5.4-n= 5

n= 0.4

ANSWER:
m= 1.8
n=0.4

Step-by-step explanation:

Ok, this problem is on construction in mathematics.

also, see attached a rough sketch of the two constructions.

The similarities, as can be seen, is that for both constructions, we need to two major points to obtain a bisector, for the line segment the major points are (A and B) and for the angle segment the points are(P and Q)

The difference between the two construction is that the line segment needs basically two bisectors to equally divide the line located at (O and P), while the angle segment needs just one bisector at (O) to bisect the angle.
