1.
5x + 3x = 8x
2.
3x + x = 3x
3.
6x + 8x = 14x
4.
9x + 3x = 12x
5.
7x + 4x = 11x
6.
10x + x = 11x
7.
3x + 2 + 4x = 7x + 2
8.
15x + 3 + x = 16x + 3
9.
2x + 5 + 6x = 8x + 5
10.
7x + 2x + 4 = 9x + 4
11.
18x + 3x + 9 = 21x = 9
12.
6x + x + 8 = 7x + 8
EXPLANATION:
If it has the same base value, just add the coefficient.
More simply put, if they have an 'x' in front of them, just add the number before the 'x.'
You can't add a value with an 'x' in front and a value that doesn't
or example, you can't add 12x and 3

EXPLANATION
Find the highest common factor and divide the expression by this value
Place the HCF outside the brackets
Quick test: If you multiply the value outside the brackets by what is on the inside, it should give the original expression
