Solve the system:
5y+8(x−3y)=7x−12
9x+3(x−9y)=11y+46

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

Step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
