Answer:
100.
Step-by-step explanation:
When an equation like this shows ip, the best way to solve it is by using B(brackets) I(indices*such as minus numbers) D(divide) M(multiply) A(add) S(subtract)
So we would do, (5+30÷10) first, because B(brackets is first). Divide comes before add, so we do 30÷10 first which is, 3. Then we do 5+3, which is 8. Now we would do the other section, 10x5+42. We do 10x5 first (becuase multiply is before add) which is, 50. Then we do, 50+42 which is, 92. Now with both our final answers we add them together, 92+8=100.
Hope this helped in some way (p.s this is how I do it in my school)
