Plot the graph of 2x -4y = 4 (I am assuming that there is a "=" sign there). To do this, cover up "-4y". This leave 2x = 4 and, on dividing by 2, x = 2. Thus x=2, y=0 or (2, 0) is one point on the graph. Next cover up "2x", which leaves -4y = 4 so that y = -1 and so (0, -1) is another point on the graph. Mark these two points on a coordinate plane, join them together with a straight line and extend the line in both directions.
Repeat for the second equation. The two lines will intersect and th coordinates of their point of intersection is the solution.
Further Information:
If you mean: 2x-4y = 4 and 3x-y = 4
Coordinates of 1st line: (2, 0) and (0, -1)
Coordinates of 2nd line: (4/3x, 0) and (0, -4)
Graph the two lines on the Cartesian plane and where they intersect are the solutions to the equations which works out as x = 1.2 and y = -0.4

How do you solve combine like terms12xy 4 3xy 6?
The first step is to include the - or + values for the given terms
How do you solve -2x-10y-12 and 3x y equals 4?
-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)
How do you solve linear equation 2x plus 3xy-4y equals 10?
2x+3xy-4y=10to solve for yyour objective will be to get y by itself on one side of the equal signyou first subtract 2x to get the terms with y variables on one side3xy-4y=10-2xthen undistribute the y from the two terms to get one yy(3x-4)=10-2xnow divide 3x-4y=(10-2x)/(3x-4)theres your answer

Solve the system of equation using substitution 2x plus 5y equals 2 and -3x-y equals -3?
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
How do you solve -2x-10y-12 and 3x y equals 4?
-2x-10y-12+3xy=4Put all x's to the other side and the ones with y's on the other:-10y+3xy=4+2x+12-10y+3xy=16+2xNow you factor a y from the side with the y's:y(-10+3x)=16+2xDivide both sides by (-10+3x):y=(16+2x)/(-10+3x)
