S= to (-21) and u find s by adding a # plus 18 but the number has to be negative when the answer is negative and it has to be bigger than 18
Answer:
a= -5
Step-by-step explanation:
- times -1 to everything in the parenthesis -a+3+2a= -2
- combined like terms a+3= -2
- subtract 3 from both sides a= -2-3
So five over one fifty twoth's means 5/(1/52) to simplify, mutiply the whole fraction by 52/52 so
260/(52/52)=260/1=260
answer is 260
