Let's solve 'em all!

Original Equation:
25 = 2x + 3
-3 -3
22 = 2x
/2 /2
11 = x (So now we are looking for an equation that has the solution: 11)

A.
28 = 2x
/2 /2
14 = x

B
22 = 2x
/2 /2
11 = x

C
50 = x + 3
-3 -3
47 = x

D
25/2 = x + 3
12.5 = x + 3
-3 -3
9.5 = x

Thus, the answer is B since both 25 = 2x + 3 and 22 = 2x both are equivalent to 11.

Those two functions just miss each other so there are no real solutions. Every polynomial with complex coefficients has complex solutions.

$2x^2 + 2 = 3x$

$2x^2 - 3x = -2$

$2( x^2 - \frac 3 2 x) = -2$

$x^2 - \frac 3 2 x = -1$

$x^2- \frac 3 2 x+ (\frac 3 4)^2= -1 + (\frac 3 4 )^2$

$(x - \frac 3 4)^2 = -\frac 7{16}$

$x - \frac 3 4 = \pm \sqrt{ -\frac 7{16}}$

$x = \frac 3 4 \pm \frac i 4 \sqrt{7}$

$x = \frac 1 4(3 \pm i \sqrt{7})$

Naya [18.7K]

Answer:

- 7/30

Step-by-step explanation:

9/10 + g = 2/3

So subtract 9/10 from both sides of the equation to get g = -7/30
