Answer:
4
Step-by-step explanation: i guessed and got it right
sorry if youre looking for an actual education!!
Let's solve for b.
2b−7x=3(b−3)
Step 1: Add -3b to both sides.
2b−7x+−3b=3b−9+−3b
−b−7x=−9
Step 2: Add 7x to both sides.
−b−7x+7x=−9+7x
−b=7x−9
Step 3: Divide both sides by -1.
−b
−1
=
7x−9
−1
b=−7x+9
Answer:
b=−7x+9
4x+4=-3+2x+15
Step 1: combine like terms
4x-2x=15-3-4
2x=8
Step 2: divide by 2 on both sides
x=4
