Answer:

6 $\frac{1}{3}$

Step-by-step explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6 $\frac{1}{3}$

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13 $\frac{1}{3}$ = 13 $\frac{1}{3}$ in the end.

Hope this helps :)

A numbr increased by 4 is the same as 19 minus 2 times that number (x+4=19-2x) solve for x

k0ka [10]

$x- number\\\\
x+4=19-2x\ \ \ |Subtract\ x\\\\
4=19-2x-x\\\\
4=19-3x\ \ \ |Subtract\ 19\\\\
4-19=-3x\\\\
-15=-3x\ \ \ |Divide\ by\ (-3)\\\\
x=5\\\\
\textbf{Number\ is\ 5.}
