2X + 6X - 3 = 13
add 2X and 6X together
8X - 3 = 13
add 3 to each side
8X - 3 + 3 = 13 + 3
8X = 16
divide both sides integers by 8
(8/8)X = 16/8
X = 2
----------------check in original equation
2(2) + 6(2) - 3 = 13
4 + 12 - 3 = 13
13 = 13
checks
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7

13...... 9 plus 5 equals 14...... 14 minus 1 equals 13
It is -13.
Yes that is correct
As follows:- 4n+13 = n-8 4n-n = -8-13 3n = -21 n = -7

13...... 9 plus 5 equals 14...... 14 minus 1 equals 13
nope. It equals five. Think of it as positive 13 minus 8.
It is -13.
X +13 equals 22, X equals nine
