Answer:
2x+3y =5.....equation 1
3x+4y=26....equation 2
multiply equation 1 with 3 and equation 2 with 2
3(2x+3y )=5×3
6x+9y=15 .....equation 3
2(3x+4y)=26×2
6x+8y=52.....equation 4
from equation 3 and equation 4
6x+9y-(6x+8y)=15-52
6x+9y-6x-8y=-37
y= -37
from equation 1
2x+3y =5
2x+3(-37)=5
2x-111=5
2x=5+111
2x=116
x=116/2
x=58
