Step-by-step explanation:

Answer:

x = 3, y = -2.

Step-by-step explanation:

5x + 6y = 3

2x - 3y = 12 Multiply this by 2:

4x - 6y = 24 Now add this to the first equation:

9x = 27

x = 3.

Substitute x = 3 in the second equation:

2(3) - 3y = 12

-3y = 12 - 6 = 6

y = 6 / -3

y = -2.

Create an equation with one solution of x = −9.

7x − (x − 26) = 2x − ( + x)

Answers

1 Remove parentheses.

7x-x+26=2x−x

2 Cancel -x on both sides.

7x+26=2x

3 Subtract 7x from both sides.

26=2x−7x

4 Simplify 2x-7x to -5x.

26=−5x

5 Divide both sides by -5.

26/-5=x

how many quarts of a 75% acid solution must be mixed with 3 quarts of a 10% acid solution to make a 60% acid solution

Answers

Answer:

yes it is correct tq

Step-by-step explanation:

my friend

Answer:

10 quarts.

Step-by-step explanation:

Work with amounts of pure acid.

There is 0.10*3 quarts of pure acid in the 10% solution.

3*0.10 + 0.75x = 0.60(x + 3) where x is the number of quarts of 75% acid.

0.30 + 0.75x = 0.60x + 1.8

0.15x = 1.5

x = 10 .
