## Elementary Algebra

$0.1x+1.2$
1. Expand the algebraic expression using the distributive property: $0.3(x-4)+0.4(x+6)-0.6x$ =$0.3x-1.2+0.4x+2.4-0.6x$ 2. Rewrite the expression: $0.3x-1.2+0.4x+2.4-0.6x$ $=0.3x+0.4x-0.6x-1.2+2.4$ 3. Combine like terms to simplify: $0.3x+0.4x-0.6x-1.2+2.4$ $=x(0.3+0.4-0.6)−1.2+2.4$ $=x(0.1)+1.2$ $=0.1x+1.2$
