Solve for x: 3(x-4+1b)=8

Step-by-step answer

P Answered by Specialist

Step-by-step explanation:

$3\left(x-4+1\cdot \:b\right)=8$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3\left(x-4+1\cdot \:b\right)}{3}=\frac{8}{3}$

$\mathrm{Simplify}$

$x-4+b=\frac{8}{3}$

$\mathrm{Subtract\:}b\mathrm{\:from\:both\:sides}$

$x-4+b-b=\frac{8}{3}-b$

$\mathrm{Simplify}$

$x-4=\frac{8}{3}-b$

$\mathrm{Add\:}4\mathrm{\:to\:both\:sides}$

$x-4+4=\frac{8}{3}-b+4$

$\mathrm{Simplify}$

$x=-b+\frac{20}{3}$

Computers and Technology

A common programming operation is to swap or exchange the values of two variables. If the value of x is currently 19 and the value of y is 42, swapping them will make x into 42 and y into 19. Write a program named Swap.java that allows the user to enter two int values. The program should store those values into variables and then swap the variables. Print the values of both variables before and after the swap. You will receive full credit as long as your solution works, but try to do this using as few variables as possible
