I think the answer shouls be 80. But its not given in the options.
3(x + 2) + 4(x - 5) = 10
Use the distributive property:
3x + 6 + 4x - 20 = 10
Combine like terms:
7x -14 = 10
Add 14 to both sides:
7x = 24
Divide both sides by 7:
x = 24/7

Answer:
The answer is $31,722.
Step-by-step explanation:
10,000 x 1.08 = 10,800
Do this 14 more times, your answer times 1.08.
You end up with 31,721.6911418.
Rounded to the nearest dollar, that would be $31,722.
Think the 4 less than but not equal to as a equal sign
step 1. isolate the variable ( variable must stand alone)
step 2. subtract 12n -12n=0
step 3. since you subtract 12n from the left you must do the same to the right.
step 4. 13n - 12n =1n
step 5. the equation should look like this -4 less than but not equal to 1n
step 6. isolate the variable n
step 6. divide 1n/1 on the right and on the left -4/1 it equals -4
so, n is -4
