Numerical Ability
Solve each of the following systems by substitution
5x - 2y = -5
y - 5x = 3
Please help, I understand the addition method but not the substitution
Read Solution (Total 1)
-
- from eqn 1
we have
5x=2y-5
so we can substitute the value of 5x in eqn 2 by (2y-5)
as
y-(2y-5)=3
-y+5=3
y=2
Hence we can find the value of x - 10 years agoHelpfull: Yes(0) No(0)
