Question

3(4x−7)=27 what does x =

Answer 1

3(4x - 7) = 27

First, divide both sides by 3. / Your problem should look like: $4x - 7 = \frac{27}{3}$
Second, simplify $\frac{27}{3}$ to 9. / Your problem should look like: $4x - 7 = 9$
Third, add 7 to both sides. / Your problem should look like: $4x = 9 + 7$
Fourth, add 9 + 7 to get 16. / Your problem should look like: $4x = 16$
Fifth, divide both sides by 4. (4 times 4 is 16) / Your problem should look like: $x = \frac{16}{4}$
Sixth, simplify $\frac{16}{4}$ to 4. / Your problem should look like: $x = 4$

Answer: x = 4

Answer 2

3(4x−7)=27

(3)(4x)+(3)(−7)=27(Distribute)

12x+−21=27

12x−21=27

Add 21 to both sides.

12x−21+21=27+21

12x=48

Divide both sides by 12.

12x/12=48/12

x=4
