Solution for 0.4(k-6)+0.03(k+30)=0.43k equation: 


Simplifying
0.4(k + -6) + 0.03(k + 30) = 0.43k

Reorder the terms:
0.4(-6 + k) + 0.03(k + 30) = 0.43k
(-6 * 0.4 + k * 0.4) + 0.03(k + 30) = 0.43k
(-2.4 + 0.4k) + 0.03(k + 30) = 0.43k

Reorder the terms:
-2.4 + 0.4k + 0.03(30 + k) = 0.43k
-2.4 + 0.4k + (30 * 0.03 + k * 0.03) = 0.43k
-2.4 + 0.4k + (0.9 + 0.03k) = 0.43k

Reorder the terms:
-2.4 + 0.9 + 0.4k + 0.03k = 0.43k

Combine like terms: -2.4 + 0.9 = -1.5
-1.5 + 0.4k + 0.03k = 0.43k

Combine like terms: 0.4k + 0.03k = 0.43k
-1.5 + 0.43k = 0.43k

Add '-0.43k' to each side of the equation.
-1.5 + 0.43k + -0.43k = 0.43k + -0.43k
