5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
5x-4 = 47 Add 4 to both sides: 5x = 51 Divide both sides by 5 to find the value of x: x = 10.2
5x+3 = x+4 5x-x = 4-3 4x = 1 x = 1/4 Thats not even close to how you solve it. First of all the equation is written 5^(x+3)=x+4. Simple Logarithms are needed to solve.
y = 5x - 4 Substitute 6 in for y; then solve for x: 6 = 5x -4 10 = 5x 2 = x So, the x-coordinate is 2.
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
If you mean: x2+5x+4 = 0 then the solutions are x = -1 and x = -4
x = .5x - 4. Get all of the x's on one side: x - .5x = .5x - .5x -4 ---> .5x = -4 Multiply each side by 2. x = -8
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
we need to know the = 5x + 4 = ????? cant solve for x without the = ??? with what you gave me the answer could be 500,000,004
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
9x-5x=4x, 7/4=1.75, x=1.75
you cant
5x-4 = 47 Add 4 to both sides: 5x = 51 Divide both sides by 5 to find the value of x: x = 10.2
3x-4=5x+6 gives: 2x=-10 which gives x=-5
