This question could be done in many ways. The easiest is by multiplying the whole equation by 2 which will get rid of the fraction.
Step One
Multiply the entire fraction by 2.
2 [ 12x + 51 = 1/2 x + 5 ]
24x + 102 = x + 10
Step Two
Subtract 102 from both sides.
24x = x + 10 - 102
24x = x - 92
Step Three. Subtract x from both sides.
24x - x = - 92
23x = - 92
Step four
Divide by 23
x = - 92/23
x = - 4
