\left(z+3\right)\times 4+z+3=z\times 2
Variable z cannot be equal to any of the values -3,0 since division by zero is not defined. Multiply both sides of the equation by z\left(z+3\right), the least common multiple of z,z+3.
4z+12+z+3=z\times 2
Use the distributive property to multiply z+3 by 4.
5z+12+3=z\times 2
Combine 4z and z to get 5z.
5z+15=z\times 2
Add 12 and 3 to get 15.
5z+15-z\times 2=0
Subtract z\times 2 from both sides.
3z+15=0
Combine 5z and -z\times 2 to get 3z.
3z=-15
Subtract 15 from both sides. Anything subtracted from zero gives its negation.
z=\frac{-15}{3}
Divide both sides by 3.
z=-5
Divide -15 by 3 to get -5.
