Answer:
We start with the equation:
A: 3*(x + 2) = 18
And we want to construct equation B:
B: X + 2 = 18
where I suppose that X is different than x.
Because in both equations the right side is the same thing, then the left side also should be the same thing, this means that:
3*(x + 2) = X + 2
Now we can isolate the variable x.
(x + 2) = (X + 2)/3
x = (X + 2)/3 - 2
Then we need to replace x by (X + 2)/3 - 2 in equation A, and we will get equation B.
Let's do it:
A: 3*(x + 2) = 18
Now we can replace x by = (X + 2)/3 - 2
3*( (X + 2)/3 - 2 + 2) = 18
3*( (X + 2)/3 ) = 18
3*(X + 2)/3 = 18
(X + 2) = 18
Which is equation B.
Answer:
3/8 is greater
Step-by-step explanation:
Answer:
x= -3
x= -1
Step-by-step explanation:
y = x ^ 2 + 4x + 3
= (x+3)(x+1)
Answer:
x = a + 8
Step-by-step explanation:
x = The number that is 40% more than five more than a number a.
x = 40% more than 5 (plus a)
5 * 0.6 = 3
5+3 = 8
x = a + 8
