Answer:
3
Step-by-step explanation:
y is given as 3
therefore
2 x 3 + 8 + 5x= 29
6 + 8 + 5x= 29
14 + 5x= 29
5x= 29 - 14
5x= 15
x= 15/5
x= 3
Answer:
Step-by-step explanation:
You expand the equation
6x + 14 = 6x - 20
6x-6x = -20 -14
x= -34
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
