Full solution

Q. Solve for a a .\newline1.66=1.1+0.2a -1.66=-1.1+0.2 a \newlineAnswer: a= a=
  1. Move Constant Term: Which operation should be used to isolate aa?\newlineIn 1.66=1.1+0.2a-1.66 = -1.1 + 0.2a, we should first move the constant term 1.1-1.1 to the left side by adding 1.11.1 to both sides of the equation.\newlineAdd 1.11.1 to both sides: 1.66+1.1=1.1+1.1+0.2a-1.66 + 1.1 = -1.1 + 1.1 + 0.2a
  2. Addition Calculation: Perform the addition on the left side of the equation.\newlineCalculate 1.66+1.1-1.66 + 1.1 to get 0.56-0.56.\newlineNow the equation is 0.56=0.2a-0.56 = 0.2a
  3. Divide by Coefficient: Now, divide both sides by the coefficient of aa, which is 0.20.2, to isolate aa.\newlineDivide by 0.20.2: 0.56/0.2=0.2a/0.2-0.56 / 0.2 = 0.2a / 0.2
  4. Division Calculation: Perform the division to find the value of aa.\newlineCalculate 0.56/0.2-0.56 / 0.2 to get 2.8-2.8.\newlineSo, a=2.8a = -2.8
