Answer:

8(4q-5)-7=5(5q-8)

32q - 40 - 7 = 25q - 40

32q - 25q = 40 -40 +7

7q = 7

q = 7/7

q = 1

28q - 40 - 7 = 25q - 40
-25q -25q
————————————
3q - 40 - 7 = 40
40 - 7 = 33

3q - 33 = 40
33 + 40 = 76
33 / 3 = 11
q = 11

Mickey and Donald earn $53 weekend after taxes Mickeys share is seven dollars greater than Donald's how much does Donald earn ea

igor_vitrenko [27]

Donald earns $23 each weekend and Mickey earns $30.

Step-by-step explanation:

Given,

Money earned by Mickey and Donald = $53

Let,

Share of Mickey = x

Share of Donald = y

According to given statement;

x+y=53 Eqn 1

x = y+7 Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$(y+7)+y=53\\y+7+y=53\\2y=53-7\\2y=46$

Dividing both sides by 2

$\frac{2y}{2}=\frac{46}{2}\\y=23$

Putting y=23 in Eqn 2

$x=23+7\\x=30$

Donald earns $23 each weekend and Mickey earns $30.
