Answer:
josh vendió 17 libros recaudando 306 dolares .
jessica vendió 255 libros recaudando 4590 dolares.
Step-by-step explanation:
Sustituimos por variables :
libros que vendió Jessica = x
libros que vendió Josh = y
entonces:
x + y = 272
Jessica vendió 15 veces mas libros que josh:
x = 15y
Reemplazamos en la anteriior ecuacion:
15y +y = 272
16y = 272
y = 17
Reemplazamos en la primela ecuacion :
x + 17 = 272
x = 255
Answer:
x = -3
Step-by-step explanation:
Step 1: Write out equation
6 - 4x = 6x - 8x + 12
Step 2: Combine like terms (x)
6 - 4x = -2x + 12
Step 3: Add 4x on both sides
6 = 2x + 12
Step 4: Subtract 12 on both sides
-6 = 2x
Step 5: Divide both sides by 2
-3 = x
Step 6: Rewrite
x = -3
Answer:
y = (3/2)x + 8
Step-by-step explanation:
Make it into y = form so...
3x - 2y = -16
-2y = -3x - 16 (subtract 3x from both sides)
y = 
x + 8 (divide both sides by -2)
