There are two variables here (x & y) for which no value has been given.
There is only one linear equation provided.
Therefore, this equation can not be solved. More information is required, such as the value of one variable or another linear equation.
Subtract by 7x and divide by 2.
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
7x = 3x - 12 4x=-12 x=-3
(3,3)
7x + 8 = 11x + 3, solve for xsubtract 7x from both sides8 = 11x - 7x + 38 = 5x + 3subtract 3 from both sides5 = 5xdivide both sides by 51 = x.
2x+3=9x 3=9x-2x 3=7x x=3/7
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
7x-3=39 7x=42 x=6
Solve for y 3y=-7x+9 y=-7/3x+3 the slope is the coefficient of x in this case, it is -7/3
you need to find the value of X first before you can solve this equation
-7x - 2y = -3
