<span>6a+14=-7-a
you simplify the equation to the form, which is simple to understand
<span>6a+14=-7-a
you move all terms containing a to the left and all other terms to the right.
<span>+6a+1a=-7-14
you need to simplify left and right side of the equation.
<span>+7a=-21
you divide both sides of the equation by 7 to get a.
<span>a=-3</span></span></span></span></span>

5(x + 3) - 3(x - 2) = 19 That should give you the result you need. The answer will come out to be x = - 1
If you want it to be - 1 to start with, then
2(5x + 3) - 13x + 2 = - 1
Answer:
18
Step-by-step explanation:
We can use a proportion to find out the number of teachers that are needed.
3/70 = x/14,700
70x = 3 * 14,700
70x = 44,100
x = 630
630 teachers are needed altogether. Since there are already 612 teachers, the number of more teachers who are needed is the difference between 630 and 612.
630 - 612 = 18
Answer: 18
