You can put this solution on YOUR website!
4^(x + 1) = 2
\n" ); document.write( "2^2(x + 1) = 2^1 {changed both to have a common base of 2}
\n" ); document.write( "2(x + 1) = 1 {since these two were equal, with same base, set exponents equal}
\n" ); document.write( "2x + 2 = 1 {used distributive property}
\n" ); document.write( "2x = -1 {subtracted 2 from both sides}
\n" ); document.write( "x = -1/2 {divided both sides by 2}
\n" ); document.write( "
