a^2+b*2=c^2 

a^2+2b=c^2

  \text{Regroup terms} 

a^2=c^2-2b
  \text{Subtract 2b from both sides} 

a=\pm \sqrt{c^2-2b}  \text{Take the square root of both sides}

El día del estreno de una película se vendieron 600 entradas y se recaudaron 196 250 soles. Si los adultos pagaban 400 soles. y
gulaghasi [49]

Por medio de sistema de ecuaciones:

*adultos (a) = $400

*niños (b) = $150

total de entradas : a + b = 600 ecua 1

dinero recaudado:

400a + 150b = 196 250 ecua 2

operamos:

a + b = 600 ecua 1

400a + 150b = 196 250 ecua 2

--------------------------

(-150) a + b = 600

400a + 150b = 196 250

-----------------------

- 150a - 150b = -90 000

400a + 150b = 196 250

-----------------------

250a = 106 250

a = 106 250/250

a = 425 adultos

a + b = 600

425+b =600

b = 600-425

b = 175 niños

comprobacion:

400a + 150b = 196 250

400(425)+150(175)=196 250

170 000 + 26 250 = 196 250

196 250 = 196 250
