Question

resolva as equaçoes do 1 grau.
a)2(1-t)+1=3(t-3)-2t

b)5(m+1)-3(2m+1)=4(5-m)

Answer 1

a) 2 (1-t) +1 = 3 (t-3) -2t
2- 2t +1 = 3t -9 -2t
3 -2t = t -9
3+9 = t +2t
12 = 3 t
12 ÷ 3 = t
4= t

b) 5 (m+1) -3 (2m+1) = 4 (5-m)

5m + 5 - 6m -3 = 20 -4m

-m +2 = 20 -4m
-m + 4m = 20 -2
3m =18
m= 18÷ 3
m=6
