6x plus 4y equals 32 -6x plus 4y equals 8?
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
What is 10x plus 3y minus 4x minus 7y equals?
6x - 4y
How much is (2x plus 3y) plus (4x plus y)?
It is the same as: 6x+4y
Describes the graph of the equations 2y equals 3x plus 2 and 4y equals 6x plus 1?
The lines are parallel.
6x plus 4y equals 32 -6x plus 4y equals 8?
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
6x - 4y equals -8 11x plus 4y equals 76?
(4, 8)
What is the answer to 6x plus 4y equals 62 and 5x plus 3y equals 51?
(9,2)
How do you solve 6x-4y equals 54 -9x plus 2y equals -69 using substitution?
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
Simplify 4x plus 7y plus 2x-3y equals?
6x plus 4y
How much is (2x plus 3y) plus (4x plus y)?
It is the same as: 6x+4y
What is 10x plus 3y minus 4x minus 7y equals?
6x - 4y
Describes the graph of the equations 2y equals 3x plus 2 and 4y equals 6x plus 1?
The lines are parallel.
What is the answer to 6x plus 4y equals -12 and 8x-14y equals -16?
x = -2 and y = 0
6x plus 18 equals 54 solving for x?
6x + 18 = 54 6x = 54 - 18 6x = 36 x = 36 ÷6 x = 6
What is the graph of 6x-6y equals -48 and -10x plus 4y equals 92?
Two straight lines that intersect.
If 6x-8y equals 10 and 2x-4y equals 7 then 4x-4y equals?
