Find the value of two numbersif their sum is 12 and their difference is 4
Sonbull [250]
We can set up a system of equations:

x + y = 12
x - y = 4

Adding these two together:

2x = 16
x = 8

Substituting 8 in the first equation:

8 + y = 12
y = 4

Hope this helps!

Anybody know how to do this? I need Help Now!!!!!

Hi there!

The answer is
x \leqslant - 5

We have the following inequality.
- 6x \geqslant 30

We can divide both sides by -6, but because we divide by a negative number, we must flip the sign.

x \leqslant 30 \div - 6
x \leqslant - 5
