Question

Write an equation with the solution x=25.The equation should have the variable on both sides,a decimal coefficient on the left side,and a decimal anywhere on the right side.One of the decimals should be written in tenths, other in hundredths.

Answer 1

`x=25\ \ \ \ \ |add\ 5x\ to\ both\ sides\\\\6x=25+5x\ \ \ \ \ |multiply\ both\ sides\ by\ 0.25\\\\\boxed{1.5x=6.25+1.25x}\\\\check:\\1.5x=6.25+1.25x\ \ \ \ \ |subtract\ 1.25x\ from\ both\ sides\\\\0.25x=6.25\ \ \ \ \ \ |divide\ both\ sides\ by\ 0.25\\\\x=25`
