Solve the following equation

20+10w=1000-15w

Solve for *w*

20 + 10w = 1000 - 15w

Group our variables 10w and -15w

add 15w to both sides

10w + 20 + 15w = -15w + 1000 + 15w

25w + 20 = 1000

20w | |

20 |

= |

10 |

20 |

Group our constants 20 and 1000.

subtract 20 from both sides

25w + 20 - 20 = 1000 - 20

25w = 980

25w | |

25 |

= |

980 |

25 |

w = 39.2

w = 39.2
