It sounds like you want to solve for x. If so, then follow these steps:

2x-1 = r

2x-1 = 4x ... replace r with 4x

2x-1-2x = 4x-2x ... subtract 2x from both sides

-1 = 2x

2x =  -1

2x/2 = -1/2 .... divide both sides by 2

x = -1/2 is the fractional solution for x

x = -0.5 is the decimal solution for x.

--------------

If you want to figure out the value of r, then plug the x solution into the equation below and simplify

r = 4x

r = 4(-1/2)

r = -2

The correct answer is the first one.

5 x 100 is correct.
9 x 1 is correct because the 9 is in the ones section, not the tens.
3 x 1/10 is correct because it is equal to 0.3.
7 x 1/1000 is correct because it is equal to 0.007.

How many solutions does x²+3x=3 have?
aev [14]

Answer:

2 (real) solutions.

Step-by-step explanation:

A quadratic always has two solutions, whether they are real or complex.

Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).

In the case of

x^2+3x = 3, or

x² + 3x -3 = 0

we apply the quadratic formula to get

x =  (-3 +/- sqrt(3^2+4(1)(3))/2

to give the two solutions

{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}

both of which are real.
