Solve 7b+3-4b=3-3(b+4)

$$7 b + 3 - 4 b = 3 - 3 ( b + 4 )$$

Solve for b

$$b=-2$$

Steps for Solving Linear Equation

Combine 7b and -4b to get 3b.

$$3b+3=3-3\left(b+4\right)$$

Use the distributive property to multiply -3 by b+4.

$$3b+3=3-3b-12$$

Subtract 12 from 3 to get -9.

$$3b+3=-9-3b$$

Add 3b to both sides.

$$3b+3+3b=-9$$

Combine 3b and 3b to get 6b.

$$6b+3=-9$$

Subtract 3 from both sides.

$$6b=-9-3$$

Subtract 3 from -9 to get -12.

$$6b=-12$$

Divide both sides by 6.

$$b=\frac{-12}{6}$$

Divide -12 by 6 to get -2.

$$b=-2$$
