Answer:
The equation is a conditional.
y = 7.5
Step-by-step explanation:
y - 11 + 3y = 6y + 4
4y - 11 = 6y + 4
4y - 4y - 11 = 6y - 4y + 4
- 11 = 2y + 4
- 11 - 4 = 2y + 4 - 4
2y = - 15
2y ÷ 2 = - 15 ÷ 2
y = - 7.5
Rounding off to thousandths is referring to the hundredth number(3rd number from right)
if it's >5, it +1 to the thousand's number (4th number from right),
eg. 4570 rounded off by thousand = 5000
if <5 then it reduces to 0.
eg. 3489 rounded off by thousand = 3000
for your case, 2,181,465 rounded off to thousand = 2,181,000
