Mathematics

Answer:

The first number is 14

The second number is -3

Step-by-step explanation:

x + 2y = 8

2x + y = 25

Solving simultaneously,

2x + 4y = 16

2x + y = 25

On subtracting, we have

3y = -9

y = -3

Going to substitute for y, we have

x + 2(-3) = 8

x - 6 = 8

x = 14

Pls give two answers for good measure
katrin2010 [14]

Step-by-step explanation: To solve for x in this inequality,

your goal is the same as it would be if you were solving an

equation, to get x by itself on one side.

Since 5 is being subtracted from x, add 5 to both sides of the inequality.

On the left, the -5and +5 cancel out and on the right, -2 + 5 is 3.

So we have x ≥ 3.

When graphing, start with a closed dot at +3 because x is

not just greater than +3, it's equal to it as well.

Then draw an arrow to the right, like I have done below.
