Question

resolver cada ecuacion.
c) x+(x+1)+(x+2) = 48
d) x+(x-10)+(x-15)=575.​

Answer 1

Respuesta:

Explicación paso a paso:

c)

x + (x+1) + (x+2) = 48

x + x + 1 + x + 2 = 48

3x + 3 = 48

3x = 45

x = 15

d)

x + (x-10) + (x-15) = 575

x + x - 10 + x - 15 = 575

3x - 25 = 575

3x = 600

x = 200

Answer 2

c)x+x+1+x+2=48

x+x+x=-1-2+48

3x=45

x=45÷3

x=15

d)x+(x-10)+(x-15)=575

x+x-10+x-15=575

x+x+x=10+15+575

3x=600

x=600÷3

x=200
