We'll remove the brackets:
3v - 39 + 4 < 10
We'll isolate the term in v to the left side and we'll move all the numbers alone to the right side:
3v < 10 + 39 - 4
3v < 45
v < 15
The inequality is satisfied by all values of v, smaller than 15, excepting the value of 15: v < 15.
3v-39+4<10 (open the brackets)
3v<10+39-4 (take all the constants on one side)
v<45/3 (divide by 3 on the other side to get v)
The inequality that satisfies the equation is v<15 therefore all the values less then 15 can satisfy this equation.
