First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule
4 -2(-5a -10) = 30
4 + 10a + 20 = 30
Now you need to add 4 and 20 because they are on the same side
24 + 10a = 30
Now subtract 24 on both sides
24 + 10a = 30
-24. -24
10a = 6
Last divide 10 from both sides
10a/10. = 6/10
a= 6/10
Last simplify (optional but recommended)
a = 3/5 or 0.6
Hope this helped :)
A = 0.6

Answer:
y=6
2y=12
Step-by-step explanation:
GHIJ and KLMN's ratio is 1:4
since these two shapes are similar the ratio of HI and LM is 1:4
so if LM is 24, HI will be 6:24
HI=y=6
