x = 4
To check the solution, substitute x = 4 back into the original equation:
22 = 7(4) + 6 - 5(4)
22 = 28 + 6 - 20
22 = 34 - 20
22 = 14
Since 22 does not equal 14, the solution x = 4 is incorrect. There is no solution to the equation.

Apologies for the incorrect solution.
Let's solve the equation correctly:
22 = 7x + 6 - 5x
First, combine like terms:
22 = 2x + 6
Next, isolate the variable term by subtracting 6 from both sides:
22 - 6 = 2x
16 = 2x
Finally, divide both sides by 2 to solve for x:
x = 16/2
x = 8
To check the solution, substitute x = 8 back into the original equation:
22 = 7(8) + 6 - 5(8)
22 = 56 + 6 - 40
22 = 62 - 40
22 = 22
Since 22 equals 22, the solution x = 8 is correct.
