Answer: 4*p=8
Step-by-step explanation:
<em>You can use inverse operation to answer this equation.</em>
- <em>write out you problem: 4 x p =8</em>
- <em>The inverse of multiplication is division</em>
- <em>you do 4/4 which gives you one but the 4 will cancel itself out</em>
- <em>Do 8/4 which gives you 2</em>
- <em>under the equation write p = 2</em>
- <em>And be sure to line the p up with the p, the equal sign with the equal sign, and the 2 stays where it is ( which should be already lined up with the 8)</em>
6x + 5y = 7
-6x - 9y = -9
-4y = -2
y = 1/2 or 0.5
2x + 3(1/2) = 3
2x + 1.5 = 3
2x = 1.5
x = 0.75
Hello!
It might be a bit sloppy, but I got a picture, from left to right, I labeled each 1-4.

Answer: 140
Oleg, Sasha, and Dima shared 600 toys. Sasha had twice as many toys as Oleg. Dima had 40 more toys than Oleg.
Let the number of toys Oleg has = x
Let the number of toys Sasha has = y
Let the number of toys Dima has = z
Sasha had twice as many toys as Oleg
So y = 2*x= 2x
Dima had 40 more toys than Oleg.
z = x + 40
Oleg, Sasha, and Dima shared 600 toys
x + y + z= 600
We know y=2x and z=x+40
Replace it for y and z
Subtract 40 on both sides
Divide by 4 on both sides
Oleg had 140 toys
