Answer:
5y+8(x-3y)=7x-12
5y+8x-24y=7x-12
8x-7x + 5y-24y= -12
X - 19y = - 12
9x+3(x-9y) =11y+46
9x+3x - 27y = 11y + 46
12x -27y - 11y = 46
12x - 38y = 46
Now joining together
X - 19y = - 12
12x - 38y = 46
Multiple by 12 the first equation and Substract after
12x - 228y = -144
12x - 38y = 46
- 190y = -98
Y = 1.9
12x - 38y = 46
12x - 38(1.9) = 46
12x - 73.67 = 46
12x = 46 + 73.67
12x = 119.67
X = 9.97
So the answer are :
X = 9.97
Y = 1.9
