Combine the same terms. 14n - 7n= 7n.
The equation becomes 7n+2=38.
Subtract 2 from each side. 7n+2-2=38-2.
The equation becomes 7n=36.
Divide each side by 7 to get n on its own. 7n/7 = 36
Finally, n=5 & 1/7 or 5.142857
Best of luck!
Write the word problem as a math equation… horrible I know:
A + B + C = 22 Equation 1.
(A + B + C + D)/4 = 8 Equation 2.
Now substitute in Equation 1 into Equation 2. (A + B + C = 22)
(22 + D)/4 = 8
Now multiply both sides of the equation by the...
p – 5 – 13p = 150 – 11
Step 1: Gather the same terms all together, i.e. all the p's and all the numbers.
one p less 13p = the negative of 13p less 1p (different explanation if this helps more in the future)
Now we have - 12p -5 = 139 or (150 - 11)
Now the numbers...
