Question

Solving by Elimination method
(Algelorai Ally) and Geomelvi Ally
1) x+y=5, 2x-3y=4
2) 7 3x+4y=10. x 2x-2y=2
3) 7 37-54–4=0, que = 2 Y+7
4) 3a +2b=12, 2a+36=13
5) 7 2a+3b=18, 3a +26=17
6) 7 22+36 = 14, 3a+2b = 16
7) 2a+ 3b=21,32 +26=19
8) 7 2a+36=23, 30+26=22
9) 10%+3y = 75, 64-5y=1​

Answer 1

x+y=5, 2x-3y=4

2(x+y=5)

2x + 2y=5

2x-3y-2x-2y=4-5

y = -1

x+y=5

x+(-1)=5

x-1=5

x=5+1

x=6

Solution is x =6 and y=-1

Hope it helps

Sorry but this is the only part I know how to solve.
