Answer:
x=3
y=13
Step-by-step explanation:
okay so what that means is that the two equations are y=-x+16 and y=3x+4
so y+x=16
y-3x=4
so 4x=12 so x=3
y=13 is the solution

e.g. Rounding off 10,999 to the nearest thousand is 11,000
In this example, the least figure, the thousand figure should have to be rounded off to 2 significant figures is 5 and the greatest figure it can have is 9
