You can put this solution on YOUR website!
a = alison's age now..
\n" ); document.write( "f = he father's age now.
\n" ); document.write( "a = f - 26
\n" ); document.write( "f + 4 = 3 * (a + 4)
\n" ); document.write( "you need to solve these two equations simultaneously.
\n" ); document.write( "in the second equation, replace a with f - 26 to get:
\n" ); document.write( "f + 4 = 3 * (f - 26 + 4)
\n" ); document.write( "combine like terms to get:
\n" ); document.write( "f + 4 = 3 * (f - 22)
\n" ); document.write( "simplify to get:
\n" ); document.write( "f + 4 = 3 * f - 66
\n" ); document.write( "subtract 3 * f from both sides of the equation and subtract 4 from both sides of the equation to get:
\n" ); document.write( "f - 3 * f = - 66 - 4
\n" ); document.write( "combine like terms to get:
\n" ); document.write( "-2 * f = -70
\n" ); document.write( "divide both sides of this equation by -2 and solve for f to get:
\n" ); document.write( "f = -70 / -2 = 35
\n" ); document.write( "her father's current age is 35.
\n" ); document.write( "her current age is 35 - 26 = 9.
\n" ); document.write( "in 4 years, she will be 13.
\n" ); document.write( "in 4 years, he will be 39.
\n" ); document.write( "39 is 3 * 13.
\n" ); document.write( "father's current age and alison's current age are confirmed to be good.
\n" ); document.write( "solution is that alison is currently 9 years old.\r
