What else can I help you with?
2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
What lines would these be 2x plus 5y equals 6 and 5x-2y equals 8?
2X + 5Y = 6 5Y = - 2X + 6 Y = - 2/5X + 6/5 ----------------------------------and 5X - 2Y = 8 2Y = - 5X + 8 Y = - 5/2 + 4 ------------------- Look like intersecting lines, though not perpendicular
What is 2x equals 12 and y equals 5x?
x=6 y=30
What is 5x plus 1 equals 2x-5?
5x - 2x = -5 - 1 ie 3x = -6 so x = -2
5x plus 6-2x equals -5-x?
5x+6-2x=-5-x 3x+6=-5-x 4x=-11 x=11/-4
5x-8 equals -2x plus 6?
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
What is 6 plus 2x equals 5x plus 9?
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
2x-4 plus 3 equals 5x-6?
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
What is answer to 5x-4 equals 3x plus 6 equals?
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
8x-7 plus 2x equals 6 plus 5x plus 2?
8x-7 plus 2x equals 6 plus 5x plus 2?
3x plus 5x equals 2x plus 2?
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
2x plus 6 equals -6 5x plus 7y equals 1?
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
What lines would these be 2x plus 5y equals 6 and 5x-2y equals 8?
2X + 5Y = 6 5Y = - 2X + 6 Y = - 2/5X + 6/5 ----------------------------------and 5X - 2Y = 8 2Y = - 5X + 8 Y = - 5/2 + 4 ------------------- Look like intersecting lines, though not perpendicular
What is 5x plus 6 equals 2x plus 15?
5X + 6 = 2X + 15 -2X -2X 3X + 6 = 15 -6 -6 3X = 15 ---- ----- 3 3 x = 5 im so smart.
What is 2x equals 12 and y equals 5x?
x=6 y=30
What is 5x plus 1 equals 2x-5?
5x - 2x = -5 - 1 ie 3x = -6 so x = -2
What is the answer to 2x - 5x plus 6.3 equals -14.4?
What is the answer to 2x - 5x plus 6.3 equals -14.4?
