4x � 5t = 18
6x +10t =(-8)
2(4x-5t)+(6x+10t)= 36-8
8x-10t+16x +10t= 24
24x=24
x=1
y= -14/5

find the solution to the system by the addition method. Check your answers.
4x � 5t = 18 ----- (i)
6x + 10t = -8 ----- (ii)
8x - 10t = 36 ----- (iii) ---- Multiplying eq (i) by 2

14x = 28 ---- adding eqs (ii) & (iii)

x =

Substituting 2 for x in eq (i), we get: 8 - 5t = 18

-5t = 10

t = =

I'm sure you can at least do the check yourself!!
