Question

Which equation has the solution x = 5?

Answer 1

Answer:

Here are your answers!

Step-by-step explanation:

x/5+5=6 is x=5.

18-2x=9 is NOT x=5, it is x=9/2

32-4x=12 is x=5.

11+6x=22 is NOT x=5, it is x - 11/6

3x+1=9 is NOT x=5, it is x = 8/3

25/x+4=9 is x=5.

Answer 2

Answer:

$\boxed{\bigstar \:\:\sf \cfrac{x}{5}+5=6}$

$\boxed{\bigstar\:\:\sf 32-4x=12}$

$\boxed{\bigstar\:\:\sf \cfrac{25}{x}+4=9}$

_______________

$\sf \cfrac{x}{5}+5=6$

Subtract 5 from both sides:

$\sf \cfrac{x}{5}+5-5=6-5$

$\sf \cfrac{x}{5}=1$

Multiply both sides by 5:

$\sf \cfrac{5x}{5}=1\times \:5$

$\boxed{\bold{x=5\: \:\checkmark }}$

~~~~~~~~~~~~~~~

$\sf 18-2x=9$

Subtract 18 from both sides:

$\sf 18-2x-18=9-18$

$\sf -2x=-9$

Divide both sides by -2:

$\sf \cfrac{-2x}{-2}=\cfrac{-9}{-2}$

$\boxed{\bold{ x=\cfrac{9}{2}}}$

~~~~~~~~~~~~~~~

$\sf 32-4x=12$

Subtract 32 from both sides:

$\sf 32-4x-32=12-32$

$\sf -4x=-20$

Divide both sides by -4:

$\sf \cfrac{-4x}{-4}=\cfrac{-20}{-4}$

$\boxed{\bold{x=5\:\: \checkmark }}$

~~~~~~~~~~~~~~~

$\sf 11 + 6x = 22$

Subtract 11 from both sides :

$\sf 11+6x-11=22-11$

$\sf 6x=11$

Divide both sides by 6:

$\sf \cfrac{6x}{6}=\cfrac{11}{6}$

$\boxed{\bold{x=\frac{11}{6}}}$

~~~~~~~~~~~~~~~

$\sf 3x + 1 = 9$

Subtract 1 from both sides :

$\sf 3x+1-1=9-1$

$\sf 3x=8$

Divide both sides by 3:

$\sf \cfrac{3x}{3}=\cfrac{8}{3}$

$\boxed{\bold{x=\frac{8}{3}}}$

~~~~~~~~~~~~~~~

$\sf \cfrac{25}{x}+4=9$

Subtract 4 from both sides:

$\sf \cfrac{25}{x}+4-4=9-4$

$\sf \cfrac{25}{x}=5$

Multiply both sides by x:

$\sf 25=5x$

Let's Switch sides:

$\sf 5x=25$

Divide both sides by 5:

$\sf \cfrac{5x}{5}=\cfrac{25}{5}$

$\boxed{\bold{ x=5\:\: \checkmark }}$
