Question

x+4=3x
What's x equal please show work

Answer 1

x+4=3x

first subtract x from both sides(x-x and 3x-x)

4=2x

Now divide 2 from both sides (2x/2 and 4/2)

2=x

So x=2

Answer 2

$Solution, solve\:for\:x,\:x+4=3x\quad :\quad x=2$

$Steps:$

$x+4=3x$

$\mathrm{Subtract\:}4\mathrm{\:from\:both\:sides},\\x+4-4=3x-4$

$\mathrm{Simplify},\\x=3x-4$

$\mathrm{Subtract\:}3x\mathrm{\:from\:both\:sides},\\x-3x=3x-4-3x$

$\mathrm{Simplify},\\-2x=-4$

$\mathrm{Divide\:both\:sides\:by\:}-2,\\\frac{-2x}{-2}=\frac{-4}{-2}$

$\mathrm{Simplify},\\\frac{-2x}{-2},\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{-b}=\frac{a}{b},\\\frac{2x}{2},\\\mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1,\\x,\\Then,\\\frac{-4}{-2},\\\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{-b}=\frac{a}{b},\\\frac{4}{2},\\\mathrm{Divide\:the\:numbers:}\:\frac{4}{2}=2,\\x=2$

$\mathrm{The\:Correct\:Answer\:is\:x=2}$

$\mathrm{Hope\:This\:Helps!!!}$
