Answer 2

Answer:

(15a × 10) ÷ 50 - (45/5) = 3

Step-by-step explanation:

We can make a more complicated version of this equation but still equal to 12.

We get as follows

(15a × 10) ÷ 50 - (45/5) = 3

Parenthesis gives us

150a ÷ 50 - 45/5 = 3

Further simplifying this gets

3a - 45/5 = 3

We simplify 45/5 getting

3a - 9 = 3

We add 9 to both sides getting

3a = 12

Which is equal to the starter equation given! So, one answer is (15a × 10) ÷ 50 - (45/5) = 3!
