Best Answer

y = 3x

3x + 4y = 30

3x + 4(3x) = 30

3x + 12x = 30

15x = 30

x = 2

y = 3x

y = 3(2)

y = 6

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

2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?

2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41


How do you rewrite -3X plus 4Y equals 11?

4y = 3x+11 or as y = 3/4x+11/4


Is 3x plus 2y equals 15 and 6x plus 4y equals 30 Consistent or inconsistent?

We will see. 3X + 2Y = 15 6X + 4Y = 30 I do not like the look of elimination, so substitution 3X + 2Y = 15 3X = 15 - 2Y X = 5 - 2/3Y -------------- 6(5 - 2/3Y) + 4Y = 30 30 - 12/3Y = 30 30 - 4Y = 30 this is inconsistent in approach 3(5 - 2/3Y) + 2Y = 15 15 - 15/3Y = 15 another bad approach, try elimination to show inconsistency - 2(3X + 2Y = 15) 6X + 4Y + 30 -6X - 4Y = - 30 6X + 4Y = 30 I think it is safe to say these systems of equations are inconsistent --------------------
