Solve each eq simultaneously, because when u do when u get x or y value same as (3,5) that equation will be ur answer
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

Answer:The chocolate in the box is 3000 grams.
Every Kilogram has 1000 grams
You multiply 1000×3=3000
We can know from the pic
2x+38=90
so, x=26
