What is the order pair for x plus y equals 10 and y equals x plus 8?

x = 1, y = 9. Here's one way to solve:
Since y = x + 8, from the second equation, substitute (x + 8) for y in the first equation: x + (x+8) = 10 --> 2x + 8 = 10, and 2x = 2, so x = 1.
Now y = x + 8, so substitute x=1 and get y = 1 + 8 = 9. Check your answer in the first equation: [x+y=10]: 1+9=10, which checks out.

-x plus 5y equals 10 and -5x plus 2y equals 27?
This is a system of equations:-x + 5y = 10-5x + 2y = 27Multiply the first equation by 5.-5x + 25y = 50Subtract the 2 equations:23y = 23Solve:y = 1-x + 5(1) = 10-x = 5x = -5Thus, the ordered pair is (-5, 1).
X plus 4 equals 10?
10-4=6
What is the ordered pair the is th solution to these equations x equals 5y and 2x - 3y equals 14?
(10, 2)
6x plus 10 plus 4x equals 50?
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
What is 4x plus 20 equals 60?
x = 10
The order pair for x plus 7y equals 12 and 3x - 5y equals 10?
x = 5, y = 1
The order pair for 2x plus 4y equals 28 and x - 2y equals 10?
x = 12, y = 1
5x plus 3y equals 13 as a ordered pair?
If 5x plus 3y equals 13, the x equals 2 and y equals 1. This is because 5x2=10 and 3x1=3, and 10+3=13.
IF 2 plus 3 equals 10 7 plus 2 equals 63 6 plus 5 equals 66 8 plus 4 equals 96 THEN 9 plus 7 equals?
The answer is 144. The compound operator for (a) and (b) in each pair is a * (a+b). For 9 and 7, this is 9 x (9+7) = 9 x 16 = 144.
-4 plus 10 equals?
-4 plus 10 equals 6.
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
Which ordered pair is a soultion of the linear system 2x plus y equals 10 and 3y equals 2x plus 6?
x = 3 and y = 4 so the lines intersect at (3, 4)
What is 5 plus 10 divided by 5?
By listed sequence, it is 5 plus 10 = 15 divided by 5 equals 3. By order of operations, it is 5 + (10/5) = 5 + 2 equals 7.
