Answer:

18x + 13y = 60

6x + 2y = 6 ---> 6x = -2y +6 ---> 18x = -6y+18

Substitution

(-6y +18)+13y =60

       -18           -18

--------------------------

7y = 42 so y=6

Then, 6x + 2(6) =6, which you will get x = -1

(-1, 6)

Answer:

The solution is (-1, 6).

Step-by-step explanation:

Rewrite 18x+13y=60 6x+2y=6 as

18x+13y=60

6x+2y=6

and then mult. the 2nd equation by -3:

18x+13y=60

-18x - 6y= -18

Sum up the two equations:

18x+13y=60

-18x - 6y= -18

------------------

         7y = 42, so y = 6.

Subbing 6 for y in the first equation results in:

          18x + 13(6) = 60, which can be reduced to 3x + 13 = 10

Then 3x = -3, and x = -1.

The solution is (-1, 6).

Please help on two math questions. I don’t understand how to do them.
Sidana [21]

When you represent intervals on the number line, you're including full dots, excluding empty dots, and you're considering numbers highlighted by the line.

In the first case, you've highlighted everything before -2 (full dot, thus included), and everything after 1 (empty dot, excluded). So, the set would be

x\leq -2 \lor\ x>1

or, in interval notation,

(-\infty,-2]\cup (1,\infty)

In the second case, you are looking for all numbers between -3 and 5. This interval is symmetric with respect to 1: you're considering all numbers that are at most 4 units away from 1, both to the left and to the right.

This means that the difference between your numbers at 1 must be at most 4, which is modelled by

|x-1|\leq 4

where the absolute values guarantees that you'll pick numbers to the left and to the right of 1.
