Answer:
no
Step-by-step explanation:
first simplify or solve the original expression ( 3(x + 11/2)-3 )
1. Parenthesis go first so do the 11/2 = 5.5 (x+5.5)
2. Distribute the 3 to the parenthesis (3x + 16.5)
3. subtract 3 from the expression (3x + 13.5)
Compare new equation with 3x + 11/2. Are they the same? (3x+13.5 vs. 3x + 11/2)
They are not the same thing.
-4,3.5
1st one
x-2x-20 = 12
-x = 32
x=-4
2nd one
-15=15q-50 - 5q
35= 10q
q = 3.5
12x=-72 //:12
12x:12=-72:12
x=-6
225+40+1,400=?
