Solve for x. 48=12+(9)/(10)x Answer: x=

Isolate x term: Isolate the term containing x on one side of the equation. To do this, we need to subtract 12 from both sides of the equation to get the term with x by itself on one side. 48 - 12 = 12 - 12 + (9/10)x 36 = (9/10)xMultiply by reciprocal: Solve for x by multiplying both sides of the equation by the reciprocal of (9/10), which is (10/9). (10/9) * 36 = xPerform multiplication: Perform the multiplication to find the value of x. x = (10/9) * 36 x = 10 * 4 x = 40

48=12+\frac{9}{10} x

\newline

Answer:

x=

Isolate x term: Isolate the term containing x on one side of the equation. $\newline$ To do this, we need to subtract $12$ from both sides of the equation to get the term with x by itself on one side. $\newline$ $48 - 12 = 12 - 12 + \left(\frac{9}{10}\right)x$ $\newline$ $$36$ = \left(\frac{$9$}{$10$}\right)x
Multiply by reciprocal: Solve for $x$ by multiplying both sides of the equation by the reciprocal of $\frac{9}{10}$, which is $\frac{10}{9}$.$\frac{10}{9} \times 36 = x$
Perform multiplication: Perform the multiplication to find the value of $x$.$x = (\frac{10}{9}) \times 36$$x = 10 \times 4$$x = 40$
