El precio de un cuaderno es mayor que la mitad del precio de un lápiz disminuido en $5. Si el cuaderno cuesta $18, ¿qué precio puede tener el lápiz? (a). L < 41
(b). L < 33
(c). L < 22
(d). L < 27

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
