Y=9x-2
3x-2y=7
3x-18x+4=7
-15x=3
x=-1/5
y= -19/5
-10(1-9x) +6(x-10)
-10+90x+6x-60
96x-70
so d is the answer
The answe is D bc 20-10 both have an x and 5 doesn’t so ur subtracting like it said and then dividing 5 since it doesn’t have the same symbol
It's just a^3...
You can check to see if this's right
