To solve this equation, we need to first simplify the left side of the equation:
(1,2-х) + 1
= 1.2 - х + 1 (rearranging the terms)
= 2.2 - х
Now, we can set this equal to 1.8 and solve for х:
2.2 - х = 1.8
Subtract 2.2 from both sides:
2.2 - х - 2.2 = 1.8 - 2.2
-х = -0.4
Divide by -1 on both sides:
х = 0.4
Therefore, the solution to the equation (1,2-х) + 1 = 1.8 is х = 0.4.
