1.2(2d+2)=4.8-(0.6+3)

Solution for 1.2(2d+2)=4.8-(0.6+3) equation:

Simplifying
1.2(2d + 2) = 4.8 + -1(0.6 + 3)

Reorder the terms:
1.2(2 + 2d) = 4.8 + -1(0.6 + 3)
(2 * 1.2 + 2d * 1.2) = 4.8 + -1(0.6 + 3)
(2.4 + 2.4d) = 4.8 + -1(0.6 + 3)

Combine like terms: 0.6 + 3 = 3.6
2.4 + 2.4d = 4.8 + -1(3.6)

Multiply -1 * 3.6
2.4 + 2.4d = 4.8 + -3.6

Combine like terms: 4.8 + -3.6 = 1.2
2.4 + 2.4d = 1.2

Solving
2.4 + 2.4d = 1.2

Solving for variable 'd'.

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

Add '-2.4' to each side of the equation.
2.4 + -2.4 + 2.4d = 1.2 + -2.4

Combine like terms: 2.4 + -2.4 = 0.0
0.0 + 2.4d = 1.2 + -2.4
2.4d = 1.2 + -2.4

Combine like terms: 1.2 + -2.4 = -1.2
2.4d = -1.2

Divide each side by '2.4'.
d = -0.5

Simplifying
d = -0.5
