Divide 2 and 4 by 2. The two turns into a 1, and the equation would then look like: 3x=1/2.

Solve 5x2 minus 3x minus 1 equals 0?
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
How do you solve 2xplus 1 over 3x equals xminus 1 over 5x?
one way to solve an equation in this format, "a/b = c/d", is to multiply both sides by "b"and by "d". You're effectively "cross multiplying" the fractions: (2x + 1) / 3x = (x - 1) / 5x ∴(2x + 1)(5x) = (x - 1)(3x) ∴10x2 + 5x = 3x2 - 3x You can then factor an "x" out of both sides ∴10x + 5 = 3x - 3 And rearrange to solve: ∴10x - 3x = -3 -5 ∴7x = -8 ∴x = -8/7
Could you Solve the following equation 3x-1 equals 7?
3x-1 = 7 3x = 8X= 8/3 = 2+2/3
How can you solve 3x-4y16 letting y equals -1?
That's not an equation you can solve, since it doesn't have an equal si Assuming you mean: 3x - 4y = 16 For a start, you should replace y with -1. Then solve the resulting equation: 3x - 4(-1) = 16 for x.
3x-y equals -1?

Solve equation 32x-1 equals 5-3x-2?
x equals 4 over 35
What is 3x over 6 1 equals 7 solve for x?
3x/61 = 7 3x/61 = 7/1 cross multiply 3x = 427 divide by 3 to both sides x = 142.333... x = 142 1/3
Solve 5x2 minus 3x minus 1 equals 0?
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3

How do you solve 3x plus 4 equals 7?
3x + 4= 7 3x= 7-4 3x/3 = 3/3 x=1

Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
How do you solve the equation for x -4 over 3x equals 1 over 7?
x = 7 7-4/3 x 7 = 1/7 3/21 = 1/7
What is 2 over 3x equals 4?
"2 over 3x equals 4" is an equation in a single variable, x.2/(3x) = 4 => 3x/2 = 1/4 => 3x = 2/4 = 1/2 => x = 1/6.
3x-y equals -1?

Y equals -3x plus 1?
you mean: y= -3x+1 y+x=-3+1 solve -3+1= -2 y+x = -2
