Hi!! so here i’ll explain: for the first one, a times 3 is 3a. so you have 3a=-30. then you divide both sides by 3 and you have a=-10!! do the same for the rest, hope this helps
Hello there, and welcome to Brainly!
In the following, you are adding the fractions together. Remember that, when adding or subtracting fractions, the denominator (bottom number in the fraction) must be the same. What you do to the denominator, you must do to the numerator as well.
Multiply 10 to both the numerator and denominator of the second fraction:
(6/10) * (10/10) = 60/100
Add across:
4/100 + 60/100 = 64/100
64/100 is your answer.
