Solve for x. -1/2 (x+5)=2x -3/2

Amiraneli [1.4K]

Start from

$-\dfrac{1}{2}(x+5)=2x -\dfrac{3}{2}$

It may be useful to multiply the whole expression by 2, in order to get rid of denominators:

$-(x+5)=4x -3$

Distribute the negative sign in the left hand side:

$-x-5=4x -3$

Move all terms involving x to the left, and all constants to the right:

$-x-4x=-3+5$

Sum like terms:

$-5x=2$

DIvide both sides -5:

$x = -\dfrac{2}{5}$

HELP ME!! SOMEBODY PLEASE HELP ME

IRISSAK [1]

6^2 = x (x - 9)
x^2 - 9x - 36 = 0
(x -12)(x + 3) = 0
x - 12 = 0; x = 12
x +3 = 0; x = -3

so in this case x = 12 then DC = 12 - 9 = 3

y^2 = 12^2 - 6^2
y^2 = 144 - 36
y^2 = 108
y = 10.4
