given is that
4x+3y=6(3x+3y)=7
i.e., 6(3x+3y)=7 &&& 4x+3y=7 ---------------(1)
3x+3y=7/6
x+y=7/18 _________(2)
multiply eqn(2) by 4
4x+4y=28/18 -------------------------(3)
(3)-(1)
4x+3y-4x-4y=7-(28/18)
y= -98/18
substitute y in eqn(2)
x-98/18=7/18
x=7/18+98/18
x=105/18.
therefore x=105/18 : y= -98/18
What else can I help you with?
Solve for x 2x plus 2y equals 8 3x plus 3y equals 6?
Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!
Solve 3x plus 4y equals 11 and x plus 3y equals 2?
x = 5, y = -1
Solve by the method of elimination 2x plus 3y equals 40 3x plus 2y equals 20?
y=16 x= -4
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
Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1

Solve the system of equations -x minus 3y equals -4 and 3x plus 5y equals 16?
If: -x-3y = -4 and 3x+5y = 16 Then: x = 7 and y = -1
What is the slope of 3x plus 3y equals 12?
The slope is -1. 3x+3y=12 Subtract 3x 3y=-3x+12 Divide by 3 y=-x+4
Is 3x plus 5y equals 12 perpendicular to 5x plus 3y equals 18?
No.
How do you solve this problem it just says solve x2 plus 3y equals 7 3x plus y2 equals 3?
x2 + 3y = 7 3x + y2 = 3 3y = x2 + 7 y2 = -3x + 3 y = x2/3 + 7/3 y = ± √(-3x + 3) If you draw the graphs of y = x2/3 + 7/3 and y = ± √(-3x + 3) in a graphing calculator, you will see that they don't intersect, so that the system of the given equations has not a solution.
What is x and y in 3x plus 3y equals 17.7 and 2x plus 3y equals 15.55?
x = 2.15 and y = 3.75
2x plus 3y equals 13 3x minus y equals 3 x equals?
2x+3y=13 3x-y=3 x=2
Find the solution 3x-3y equals 12 and 3x plus y equals 8?
70000000y=35t
What is the system of equation 3x plus 2y equals 6 and 2x plus 3y equals negative 1?
3x + 2y = 62x + 3y = -1You can use substition, elimation, or graphing to solve this system, but I prefer to use matrices. They are difficult to type out, but the answer is x = 4 and y = -3.
