Question

Barb solved the following equation: 4(3x – 12) = 5(2x + 6)

Answer 1

Answer:

4(3 * 39 – 12) = 5(2 * 39 + 6)

x = 39

Step-by-step explanation:

4(3x – 12) = 5(2x + 6)

(12x - 48) = (10x + 30)

12x - 10x = 30 + 48

2x = 78

2x/2 = x

78/2 = 39

x = 39

No Prob :)

Answer 2

x=39 is the right answer. First you had to add by 48 from both sides of the equation. And it gave us, $12x-48+48=10x+30+48$. Then simplify, and it gave us $12x=10x+78$. Next, subtract by 10x from both sides of equation. And it gave us, $12x-10x=10x+78-10x$. And then simplify, and it gave us, $2x=78$. You can also divide by 2 from both sides of the equation. And it gave us, $\frac{2x}{2}=\frac{78}{2}$. And finally, simplify and the answer is x=39 is the right answer. Hope this helps! Thank you for posting your question at here on brainly.
