The answer is 264. Simply add up all of the numbers arithmetically like you would for two plus two. To make sure the answer is correct, check your work using a calculator.
14 + 19 = 33
4x-14
A is 14
19
2n plus 7 equals 19 2n equals 12 n equals 6
yes
That equals 199
-12 + c = 19 Add 12 to both sides: c = 19+12 = 31
y = 12
12
x = 19
19 - 2*7 + 98/14 = 12.
