M + p = 48
m = 2p - 6
2p - 6 + p = 48
3p - 6 = 48
3p = 48 + 6
3p = 54
p = 54/3
p = 18 <==Pennsylvania Pigs won 18 games
m = 2p - 6
m = 2(18) - 6
m = 36 - 6
m = 30 <==Maryland Monkeys won 30 games
I presume you're trying to find n, so first remove the 7 from each side.
8n + 7 -7 = 31-7
=> 8n = 24
Then divide both sides by 8, as you want only n
8n/8 = 24/8
n = 3
She only needs 2 more candy if her main candy bar is excluded.
But if the main bar is included, she basically needs 3 candy bars to give 14 of her friends.
Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
Let x = smaller number
Let y = bigger number
y = 7x + 4
x + y = 92
x + (7x + 4) = 92
8x + 4 = 92
8x = 88
x = 11
y = 7x + 4
y = 81
