Question

Determine m e n para que:
a) (2m -3, n + 4) = (6,5)
b) (m-n, m + n) = (-3, 2)

Answer 1

a) (2m-3,n+4)=(6,5)
2m-3n=6.5-4
2m-3n=2.5
10x2m-10x3n=10x2.5
20m-30n=10x$\frac{25}{10}$
20m-30n=25
$\frac{20m}{5}- \frac{30n}{5}= \frac{25}{5}$
4m-$\frac{30n}{5}= \frac{25}{5}$
4m-6n=$\frac{25}{5}$
4m-6n=5

b) (m-n,m+n)=(-3, 2)
2-3+=-3.2
-1+2=-3.2
1=-3.2
