Answer:
x+35
Step-by-step explanation:
-10x -10y=20
-10x - 20=10y
-10x - 20/10=y
-10x - 2=y
y=-10x-2
-7x -7y=14
-7x - 14 = 7y
-7x - 14/7=y
-7x - 2=y
y=-7x-2
4x+8x+12x+16x=5+10+30+40
4x+8x+12x+16x= 85
40x=85
x= 85/40
x=2.125
279/34 = 8.20588235294
But if you would like to round it up it would be 8.2 or 8.21 depending on what you'd like to round it up to.
Let me know if this is what you mean. If not, I will fix it! :)
