Question

3(x-6)-8x=-2 + 5(2x+1)

Answer 1

Answer:

$x=-\cfrac{7}{5}$

Or

$x=-1.4$

Step-by-step explanation:

$3(x-6)-8x=-2 + 5(2x+1)$

$3(x-6)-8x \:\bold{Expand}$

$-2+5\left(2x+1\right)\:\bold{Expand}$

$-5x-18=10x+3$

$-5x-18+18=10x+3+18\:\bold{Add\:18\:to\:both\:sides}$

$-5x=10x+21$

$-5x-18+18=10x+3+18\:\bold{Subtract\:10x \:from\:both\:sides}$

$-15x=21$

$\cfrac{-15x}{-15}=\cfrac{21}{-15}\:\bold{Divide \: both\: sides\: by\: 15}$

$x=-\cfrac{7}{5}$

Answer 2

Answer:

x = -1

Step-by-step explanation:

3(x - 6) - 8x = -2 + 5(2x + 1)

3x - 18 - 8x = -2 + 10x + 5

-5x - 18 = 10x + 3

-15x = 15

x = -1
