    `Rachel can make 3 bracelets in an hour.` so can you tell how many bracelets she makes in 2 hours ?

    thats it! Rachel's function for number of bracelets made in "x" hours is \[y = 3x\]

    notice that if you plugin x=2, you do get y = 3*2 = 6 as expected

    yes he can make 4 bracelets in 2 hours but he already has 5 to start with, so in total he will be having 4 + 5 = 9, yes ?

    `Oliver can make only 2 bracelets in an hour`, 2 bracelets per hour, so the function will be \(y = 2x\) `but he already has 5 completed bracelets` adding this the overall function for Oliver is \[y=2x+5\]

  48. ganeshie8

    so the system of equations is \[y = 3x\\y=2x+5\]

    solving is easy \[y = 3x\\y=2x+5\] since the left hand sides are same, the right hand sides also must be same : \[3x = 2x+5\] solve \(x\), can you ?
