Answer:
y = 5
Step-by-step explanation:
14y + 36 = 106. subtract 36 from both sides, so now the equation is 14y = 70 because 36 is cancelled out. now divide both 14y and 70 by 14, which leaves you with y = 5
Answer:
You have to work backwards here
so if you had 100 dollars left and u spent 50 on a radio
100+50=150
Then You spent a 1/6 of it on stationery
So you mustve had 5/6 money left or 150 dollars
so you multiply that to find that
5/6=150/x
5x=900
x=180
so add 30 dolalrs to 150 and you have 180.
the you spent a third
you repeat the same process
the you have ur ANSWER
Multiply 2 and then add 4 each time
3 x 2 = 6 + 4 = 10
10 x 2 = 20 + 4 = 24
24 x 2 = 48 + 4 = 52
hope this helps
-3x + 5y = -9
4x + 8y = 12
Simplify the second,
x + 2y = 3
Times three,
3x + 6y = 9
Add to the first equation,
11y = 0
y = 0
-3x + 5(0) = -9
x = 3
Answer: x=3, y=0
