Respuesta:
a) 3x - 7 = 44; x = 17
b) 2(x + 1) = 4(8); x = 15
c) 5x - 1 = 7^2; x = 10
d) 3(x-4) = 6^3; x = 76
Explicación paso a paso:
a) 3x - 7 = 44
3x = 44 + 7
3x = 51
x = 51/3
x = 17
b) 2(x + 1) = 4(8)
2x + 2 = 32
2x = 32 - 2
2x = 30
x = 30/2
x = 15
c) 5x - 1 = 7^2
5x = 49 + 1
5x = 50
x = 50/5
x = 10
d) 3(x-4) = 6^3
3x - 12 = 216
3x = 216 + 12
3x = 228
x = 228/3
x = 76
