Depending on what your question was, there are different answers:
4x + 4 = 7x - 3
7x - 4x = 4+3
3 x = 7
x =7/3
or
4x + 47x -3 = 0
51x = 3
x = 3/51
x=1/17
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
The lines are perpendicular.
4x + 20
x can be anything, if you don't have it in an equation form, can an be an infinite amount of solutions
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
If you mean: x+4x--9 = x+1 then 4x = -8 and x = -2
The lines are perpendicular.
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
4x + 20
Without an equality sign and not knowing the plus or minus values of the given terms it can't be considered to be a straight line equation. But if you mean 4x+y = 10 then y = -4x+10 and the parallel equation is y = -4x+6
x can be anything, if you don't have it in an equation form, can an be an infinite amount of solutions
Without any plus or minus signs or an equality sign the given terms can't be considered to be an equation.
Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.
Without an equality sign and not knowing the plus or minus values of some of the given terms the given expression can't be considered to be an equation.
-4x + 4y = 1
