Question

Calcule a raiz ou solução das seguintes equações:
a) 5x + 1 = 36 *
b) 7x = 4x + 5 *
c) 9x - 7 = 5x + 13 *
d) 15x - 13 = -39 - 11x *
e) 21 + 9x = 15x + 33 *
f) 16 - 11x + 12 = -15x *
g) 2 ⋅ (2x - 1) -6 ⋅ (1 - 2x) = 2 ⋅ (4x -5) *
h) 2x + 3 ⋅ (x - 2) = 7x + 34 *
i) 4 ⋅ (x - 2) = 4 + 2 ⋅ (x - 1) *
j) 10 ⋅ (100 - x) + 2x = 3 ⋅ (x + 9) - 28 *
k) 5 ⋅ (x + 60) - 400,7 = 8 ⋅ (x - 40) *
l) 7 ⋅ (2x - 50) - 4x = 10 ⋅ (51,9 - 0,1x) *
m) 3/4 −2/3 = −5/2 *
n) /2 + 1 =/5 +1/4 *
o) /4+/3= − 100 *
p) 2/3 +5/6 =1/2 *
q) /5 = 21 −/2 *
r) 4/5 +3/4 =1/10 + *
s) (2 ⋅ (4 − 3))/3 −(4 ⋅ (4 + 5))/9 −(5 ⋅( − 4))/6 = 2 *
t) (2 + 5)/3−(4 − 9)/6=(3 − 4)/2
