Question

Identifica la incógnita y resuelve las siguientes ecuaciones: c) 3(m+1)+2=m+11 d) 2(t+3)+5=2(2t+3) ​

Answer 1

Respuesta:

c) 3(m + 1) + 2 = m + 11

3(m) + 3(1) + 2 = m + 11

3m + 3 + 2 = m + 11

3m + 5 = m + 11

3m - m = -5 +11

2m = 6

m = 6/2

m = 3

d) 2(t + 3) + 5 = 2(2t + 3)

2(t) + 2(3) + 5 = 2(2t) + 2(3)

2t + 6 + 5 = 4t + 6

2t + 11 = 4t + 6

2t - 4t = -11 +6

-2t = -5

t = -5/-2

t = 5/2

t = 2.5
