Question

resolver ecuaciones de primer grado

2x+5=19 x - 1/2 = 5/4 7 x - 11 = 38 x - 105 = 183

Answer 1

2x+5=19
2x=19-5
2x=14
x=14/2
x=7

x - 1/2 = 5/4
x=5/4+1/2
x=7/4                                                       5/4+1/2=7/4

7 x - 11 = 38
7x=38+11
7x=49
x=49/7
x=7

x - 105 = 183
x=183+105
x=288
