ab=x+2, bx=c+7 and ac=23 what is the value of x? what is ab? what is bc?
To find the value of x, we need to solve the given system of equations. Let's start by solving for x.
1. ab = x + 2
2. bx = c + 7
3. ac = 23
From equation 1, we can express x in terms of ab:
x = ab - 2
Now, let's substitute this value of x in equation 2:
b(ab - 2) = c + 7
ab - 2b = c + 7 (distribute b on the left side)
Next, we can solve equation 3 for c:
c = ac / 23
Now, substitute the value of c in equation 2:
ab - 2b = (ac / 23) + 7
This equation involves variables ab and b. To find the value of x, ab, and bc, we need additional information or numerical values for at least two of these variables. Without any more information, we cannot determine the specific values for x, ab, and bc.
