I assume that you mean
5x + y = -5
-4x + 2y = 2
Cancel the 2s from the second equation
-2x + y = 1
therefore y = 1+2x
Substitute into first equation
5x + 1 + 2x = -5
7x = -6
x = -6/7
Substitute into second equation to find that y = -5/7.

-4x plus 7y equals 9 2y equals -5x - 22?
(-4, -1)
What is x-7y plus 4x-2y simplified?
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y
What is x plus 5 plus 2y plus 4x-2?
Wat is a Buddhist temple in South East Asia and has nothing to do with x plus 5 plus 2y plus 4x -2. Incidentally, the algebraic expression is equal to 5x + 3 + 2y.
4x - 10 plus 5x equals 71?
4x - 10 + 5x = 719x = 81x = 9
5x plus 3y equals 17 5x - 2y equals -3?
Multiply the bottom equation by -1
-4x plus 7y equals 9 2y equals -5x - 22?
(-4, -1)
-5x plus 2y equals 6 -9x plus 2y equals 22?
Subtract first from second gives -4x = 16 so x = -4 and y = -7
5x plus 3y-x plus 10-2y?
5x + (3y-x) + (10-2y) = 5x + 3y - x + 10 -2y = 5x - x + 3y - 2y + 10 = 4x + y +10
What is 5x equals 4x plus 7?
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x plus 20 equals 4x plus 30?
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
What is 5x equals 4x plus 9?
5x = 4x + 9 x = 9
5x plus 2y equals 19 x - 2y equals -1?
(3, 2)
If 8x plus 5x plus 2x plus 4x equals 114 the 5x plus 3 equals?
33
What is x-7y plus 4x-2y simplified?
Splitting the equation up into the two variables: x + 4x = 5x -7y + -2y = -9y Therefore, the simplified version is: 5x - 9y
What is 3 plus 5x equals 13 plus 4x?
5x - 4x = 13 - 3 ie x = 10
What is x plus 5 plus 2y plus 4x-2?
Wat is a Buddhist temple in South East Asia and has nothing to do with x plus 5 plus 2y plus 4x -2. Incidentally, the algebraic expression is equal to 5x + 3 + 2y.
4x - 10 plus 5x equals 71?
4x - 10 + 5x = 719x = 81x = 9
