Your answer is x = 3 because if you take 150 and subtract it by both sides: 
 150 - 35x = 45
-150           -150
you have to cross out both 150 and -150, take 45 and subtract 150 which will give you -105. 
  -35x = -105 
take -35 and divide by both sides. Cross out the two -35's. Take -105/-35 which your answer is x = 3. Hopes this helps. :)

Answer: a=36; b=18
Step-by-step explanation:
 1. You know that the sum of two numbers is 54, then, you have:
 a+b=54
 2. According to the problem, the larger number is 18 more than the sampler number, this can be expressed as following:
 a=b+18
 3. Then, you must substitute the second equation into the first equation and solve for b:
 b+18+b=54
 b=18
 4. Then the value of a is:
 a+18=55
 a=36
