Firstly, you add 3 to both sides (as you've got to eliminate the -3), and this gives you;
7a=6+6a.
Then in order to get a alone, you need to subtract 6a from the right hand side (in order to counter balance) and this gives you;
1a=6
Therefore, a is equal to 6

Answer:
75
Step-by-step explanation:
The absolute value gives the positive value of any given number inside the symbol. The absolute equation is,
2.5 = I d - 2I
The values of d can be calculated through,
2.5 = d - 2
d = 4.5
Also,
-2.5 = d - 2
-2.5 + 2 = d
d = -0.5
Thus, the maximum value of the temperature is 4.5 and the minimum value of the temperature is -0.5.
In this shape there will be 540 degrees
So 98+98+115+115+x = 540
X= 114
Hope this helps!
