What is x when 2(x+3)=x-4

denpristay [2]

Answer:

$x=-10$

Step-by-step explanation:

First, use distribution to simplify

$2(x+3)=x-4\\2x+6=x-4$

Then, simplify further by combining like terms

$2x+6=x-4\\2x+10=x\\10=-1x$

times both sides by 3
3V=Bh

6 - 2/3 (x+5) = 4x solve algebraically for the exact value of x

luda_lava [24]

Answer:

x = 2

Step-by-step explanation:

1 - Rewrite

6 - 2/3 (x+5) = 4x

2 - Distribute

6 - 2/3x + 10/3 = 4x

3 - Combine like terms and get x alone

6 10/3 - 2/3x = 4x

+2/3x +2/3x

6 10/3 = 4 2/3x

------------------------------- Convert to decimals

6.3333333333.... = 4.333...x

-------------------------------- Divide both sides by 4.33...x

2 = x

Hope this helps :)
