X equals -4y 3x plus 2y equals 20?

x = -4y so 3x = -12y Substituting in the second equation, -12y + 2y = 20 or -10y = 20 ie y = -2 And then x = -4y implies that x = 8 Solution: x = 8, y = -2

3x plus 2y equals 4 -3x plus 4y equals -10?

How to find elimination method for 3x - 4y equals 30 and 3x plus 2y equals 6?

Subtract: 3x - 3x - 4y - 2y = 30 - 6 ie -6y = 24 so y = -4 and x = 14/3

Can you show me how to solve graphically 3x plus 4y equals 5 and x-2Y equals 5?

3x + 4y = 5x - 2y = 5leads to:x = 5 + 2ySo:3(5 + 2y) + 4y = 515 + 10y = 510y= -10y=-1and therefore if y = -1 then x = 3.

3x plus 2y equals 7 and 2x plus 4y equals 18?

Solve this equation using subtitution x equals 4y and 3x-2y equals 20?

3x - 2y = 20 Substitute x = 4y into this equation: 3(4y) - 2y = 20 ie 12y - 2y = 20 10y = 20 so that y = 2 and then x = 4y gives x = 2*4 = 8

What are the solutions for the equations x equals 4y and 3x-2y equals 20?

x = 4y 3x - 2y = 20 Substituting the value of x into the second equation, 3*(4y) - 2y = 20 ie 12y - 2y = 20 or 10y = 20 so that y = 2 Then x = 4y = 4*2 = 8. So (x , y) = (8 , 2)

Simplify 3x plus 2y plus 2 equals 4y plus 4?

The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1

Can you show me how to solve graphically 3x plus 4y equals 5 and x-2Y equals 5?
