Solve 2x plus 5x-1 equals 9x?
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
How do you solve 7x minus 1 equals 9 plus 5x?
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5
How do you solve 3x 4x equals 7x?
This is not possible to "solve" as such. 3x + 4x = 7x, which is the same as 7x=7x. Clearly, you end up with x=x, which is true, but not useful.This suggests that you have used the wrong method when trying to solve the problem, however your algebra was correct, since x does indeed equal x; it's when you end up with something like 2=1, or 1=0, that you have to worry.
How do you slove 3x plus 1 plus 4x-5 equals 31?
combine like terms. 3x+1+4x-5=31 3x+4x=7x 7x+1-5=31 1-5=-4 7x-4=31 then solve it 7x=35 x=5
What is 7x divided by 7x?
1
Solve 2x plus 5x-1 equals 9x?
2x + 5x - 1 = 9x 7x - 1 = 9x -1 = 9x - 7x -1 = 2x -1/2=x
How do you solve 7x-2 equals x plus 4?
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
4xy plus 1 equals 3y-7x solve for y?
4xy+1=3y-7x 4xy-3y=-7x-1 y(4x-3)=-7x-1 y=(-7x-1)/(4x-3)
How do you solve this eqation 7x plus 2 equals 3x-2 what is the value of x?
7x+2 = 3x-2 7x-3x = -2-2 4x = -4 x = -1
What is the answer to 1-5x plus 7x?
1 - 5x + 7x is an expression, not an equation (no equals sign), so you cannot solve for x. You can, however simplify (combine like terms) and get 1 + 2x.
How do you solve 7x minus 1 equals 9 plus 5x?
7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

How do you solve 3x equals 7-4x?
3x = 7 - 4x 3x + 4x = 7 - 4x + 4x 7x = 7 7x/7 = 7/7 x = 1
How do you solve -3x-1 equals 20 plus 4x?
-3x - 1 = 20 + 4x 1) the first thing you want to do is have the variable(x) in one side of the equation. so subtract so add -3x to 4x. -1 = 20 + 7x 2) now you want to isolate the variable so subtract 20 to -1. -21 = 7x 3) to solve for x you need to divide by 7 on both sides and 7x divided by 7 is one or just x and whatever you do to one side you must do to the other -21 divided by 7 is -3 x = -3
7x-3 equals 5x plus 1?
7x -3 = 5x + 1 solve for xadd three to both sides7x = 5x + 4subtract 5x from both sides2x = 4divide both sides by 2x = 2
