Answer:
3 + 4x = 36----->No
(4.3)+(4 . x)= 36------>Yes
4(3 + x)= 144--------->No
3+ x = 9-------> Yes
12 + x = 36------>No
12 + 4x = 36------->Yes
Step-by-step explanation:
The given equation is
A correct first step is to expand the LHS to get:
Or to divide through by 4 to get:
Or just distribute to get:
Answer:
-15
-5 – [-17 + (15 -6)] + (-15 - 8) – {-1 + (8 - 9) + (7 - 10)}
-5-(-17+9)+(-23)-(-1+(-1)+(-3))
-5-(-8)-23-(-1-1-3)
-5+8-23-(-5)
-5+8-23+5
=-15
