Answer: x=-2.8

Step-by-step explanation:

Given the following equation:

0.7x+6=0.3(4x+6)-2x

You can follow these steps in order to solve for "x" and find its value:

1. Apply Distributive property on the right side of the equation:

0.7x+6=0.3(4x+6)-2x\\\\0.7x+6=1.2x+1.8-2x

2. Subract 0.7x from both sides and add the like terms:

0.7x+6-(0.7x)=1.2x+1.8-2x-(0.7x)\\\\6=-1.5x+1.8

3. Subtract 1.8 from both sides:

6-(1.8)=-1.5x+1.8-(1.8)\\\\4.2=-1.5x

4. Finally, divide both side of the equation by -1.5:

\frac{4.2}{-1.5}=\frac{-1.5x}{-1.5}\\\\x=-2.8

The product of 5 and 2 less than triple a number equals the product of 7 and 8 more than twice the number. What is the number?
Oksi-84 [34.3K]

Answer:Hi,

Let the number be x

Twice the number is 2x

Five less than twice the number is 2x-5, which is given as 9

Therefore, 2x-5 = 9

or, 2x = 9+5

or, 2x = 14

or x=7

Thus the number is 7.

Cheers
