Ineed asap , jackson has saved $174 he wants to buy a electric dirt bike that costs $459 if he saves $15 dollars each week from the money he earns doing yard work and another $4 each week from his allowance how many weeks will it take jackson to save enough money for his bike? 13, 14 , 15, or 16 weeks?

$459 - $174 = $285

$15 + $4 = $19

$285 / $19 = 15

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
