Solution for 0.3(7x+28)=2.1(x+4) equation: 


Simplifying
0.3(7x + 28) = 2.1(x + 4)

Reorder the terms:
0.3(28 + 7x) = 2.1(x + 4)
(28 * 0.3 + 7x * 0.3) = 2.1(x + 4)
(8.4 + 2.1x) = 2.1(x + 4)

Reorder the terms:
8.4 + 2.1x = 2.1(4 + x)
8.4 + 2.1x = (4 * 2.1 + x * 2.1)
8.4 + 2.1x = (8.4 + 2.1x)

Add '-8.4' to each side of the equation.
8.4 + -8.4 + 2.1x = 8.4 + -8.4 + 2.1x

Combine like terms: 8.4 + -8.4 = 0.0
0.0 + 2.1x = 8.4 + -8.4 + 2.1x
2.1x = 8.4 + -8.4 + 2.1x

Combine like terms: 8.4 + -8.4 = 0.0
2.1x = 0.0 + 2.1x
2.1x = 2.1x

Add '-2.1x' to each side of the equation.
2.1x + -2.1x = 2.1x + -2.1x

Combine like terms: 2.1x + -2.1x = 0.0
0.0 = 2.1x + -2.1x

Combine like terms: 2.1x + -2.1x = 0.0
0.0 = 0.0
