2x - 3y = -4
3x + 2y = 33
Eqn(1)*2: 4x - 6y = -8
Eqn(2)*3: 9x + 6y = 99
Add the eqns: 13x = 91 so that x = 7
Substitute in eqn1: 14 - 3y = -4 so that 18 = 3y or y = 6
SOLUTION: x = 7, y = 6
-2x+3y=1 3y=1+2x y=(1+2x)/3 Then proceed to find points by plugging in given or arbitrary values of x.
it equals 13X.
2x + 4y = 72x - 2x + 4y = 7 - 2x4y = -2x + 74y/4 = -2x/4 + 7/4y = -(1/2)x + 7/4Now that y is a function of x, you can give some values for x and find the corresponding values for y. (There are infinitely values for x an y)
They intersect at points (-2/3, 19/9) and (3/2, 5) Solved by combining the two equations together to equal nought and then using the quadratic equation formula to find the values of x and substituting these values into the equations to find the values of y.

x=-3y=4
-2x+3y=1 3y=1+2x y=(1+2x)/3 Then proceed to find points by plugging in given or arbitrary values of x.
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
it equals 13X.
2x + 4y = 72x - 2x + 4y = 7 - 2x4y = -2x + 74y/4 = -2x/4 + 7/4y = -(1/2)x + 7/4Now that y is a function of x, you can give some values for x and find the corresponding values for y. (There are infinitely values for x an y)

-2
x=1
Yep. No values of X will ever repeat themselves.
What is the answer to 2x - 5x plus 6.3 equals -14.4?
2x-y+4=0... what are you actually trying to find?
yes. its 2! :)
