Solve the system by substitution.<br> 3x + y = 20<br> -7y=x<br><br> Please help
alisha [4.7K]

9514 1404 393

Answer:

  (x, y) = (7, -1)

Step-by-step explanation:

The expression for x makes it easy to use that for substitution.

  3(-7y) +y = 20

  -20y = 20 . . . . . collect terms

  y = -1 . . . . . . . . . divide by -20

  -7(-1) = x = 7 . . . use y in the second equation to find x

The solution is (x, y) = (7, -1).

Please help. 50 points + brainliest
Korvikt [17]

Answer:

1. (a-c)\sqrt{x} + b\sqrt{y}

2. 9m + 2\sqrt{n}

3. 6a

4. (5a - 3b)\sqrt{5y}

Step-by-step explanation:

1. since a and c share the same squareroot x, you can combine these together.

2. First add like terms together. 4m - m + 6m = 9m. Then 5\sqrt{n} and -3\sqrt{n} combined equals 2\sqrt{n}

3. First simplify the square roots. squareroot of 16 is 4. square root of 49 is 7. square root of 81 is 9. They are all multiplied by a in the expression. Thus 4a - 7a + 9a = 6a

4. First simplify the radicals, they are not perfect. square root of 125 is equivalent to sqrt(25 * 5), which sqrt of 25 is 5, but we keep the sqrt of 5. For sqrt of 45, it is the same as sqrt9 * sqrt5. sqrt of 9 is the same as 3 and we keep sqrt 5. Thus we get the below:

5a\sqrt{5y} - 3b\sqrt{5y}

We can combine the two like terms and get the final answer above.

please give thanks by clicking the heart :)
