4.3*(6.2-1.1)=(4.3*6.2)-(A*1.1)

Solution for 4.3*(6.2-1.1)=(4.3*6.2)-(A*1.1) equation:

Simplifying
4.3(6.2 + -1.1) = (4.3 * 6.2) + -1(A * 1.1)

Combine like terms: 6.2 + -1.1 = 5.1
4.3(5.1) = (4.3 * 6.2) + -1(A * 1.1)

Multiply 4.3 * 5.1
21.93 = (4.3 * 6.2) + -1(A * 1.1)

Multiply 4.3 * 6.2
21.93 = (26.66) + -1(A * 1.1)
21.93 = 26.66 + -1(A * 1.1)

Reorder the terms for easier multiplication:
21.93 = 26.66 + -1(1.1A)

Remove parenthesis around (1.1A)
21.93 = 26.66 + -1 * 1.1A

Multiply -1 * 1.1
21.93 = 26.66 + -1.1A

Solving
21.93 = 26.66 + -1.1A

Solving for variable 'A'.

Move all terms containing A to the left, all other terms to the right.

Add '1.1A' to each side of the equation.
21.93 + 1.1A = 26.66 + -1.1A + 1.1A

Combine like terms: -1.1A + 1.1A = 0.0
21.93 + 1.1A = 26.66 + 0.0
21.93 + 1.1A = 26.66

Add '-21.93' to each side of the equation.
21.93 + -21.93 + 1.1A = 26.66 + -21.93

Combine like terms: 21.93 + -21.93 = 0.00
0.00 + 1.1A = 26.66 + -21.93
1.1A = 26.66 + -21.93

Combine like terms: 26.66 + -21.93 = 4.73
1.1A = 4.73

Divide each side by '1.1'.
A = 4.3

Simplifying
A = 4.3
