Answer:
x= -8
Step-by-step explanation:
x-89=7(2x+3)-6 distribute 7
x-89=14x+21-6 add like terms
-13x=104 divide
x=-8
<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)

Answer:
7 to 8 hours
Step-by-step explanation:
1 * 4 = 4
5 / 6 * 4 = 20 / 6 = 3 2/6 or 3 1/3
4 + 3 1/3 = 7 1/3
