Your question is not clear because of the grammar used. So I was only able to come up to this solution: 30/100 multiply by x gives us 18. So x= 60. The total math problems are 60. James solved 18 ( 30% of 60) now he needs to solve 70% remaining of the 60 problems. So 60 - 18 = 42.
If you would like to write an equation to describe the following situation, you can do this like this:
4 apples in the morning ... 4
x ... the number of bananas Tommy eats
2 bananas for every banana that Tommy eats ... 2 * x
y ... the total number of pieces of fruit the monkey eats
The equation would be as follows: <span>y = 4 + 2 * x.</span>
