Best Answer

Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.

-7x - 2y = -3

56xy + 2y + 3x

Manipulate such that y is the subject of the equation 7x - 2y = -14 2y = 7x +14 y = (7/2)x + 7

7X + 2Y = 10 - 7X + Y = - 16 -----------------------just add 3Y = - 6 Y = - 2 --------------find X, top equation 7X + 2(- 2) = 10 7X - 4 = 10 7X = 14 X = 2 ------------check both original equations for consistency; top first 7(2) + 2(- 2) = 10 14 - 4 = 10 10 = 10 ------------top checks; now check bottom equation - 7(2) - 2 = - 16 -14 - 2 = - 16 - 16 = - 16 ------------------both check and are then consistent

y equals -1/3x plus 4/3

Subtract by 7x and divide by 2.

2y + 7x + y-1?

-7x - 2y = -3

The standard form is 7x + 2y - 3 = 0

This equation is unsolvable without knowing one of the values of either x or y.

Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0

Im guessing that the equation is 7x - 2y +3z= 19 so the answer is 7x + 3z= 19

7x = -3y + 12

7x-2y = 14 -2y = -7x+14 y = 3.5x-7

7x + y = 4y = 4 - 7x

7x + 2 = 5,6

3x - 2y + 7x + 4y = 3x + 7x - 2y +4y = (3+7)x + (-2+4)y = 10x + 2y
