1) Simplifying
5.3m + 7m
Combine like terms: 5.3m + 7m = 12.3m
12.3m
2)Simplifying
47.9w + -31.8w
Combine like terms: 47.9w + -31.8w = 16.1w
16.1w
3)Simplifying
0.3y + 4.1y + 2.5y
Combine like terms: 0.3y + 4.1y = 4.4y
4.4y + 2.5y
Combine like terms: 4.4y + 2.5y = 6.9y
6.9y
4)Simplifying
27y + -4.7y + -13.8y
Combine like terms: 27y + -4.7y = 22.3y
22.3y + -13.8y
Combine like terms: 22.3y + -13.8y = 8.5y
8.5y
5)Simplifying
3.5x + -5 + 8x
Reorder the terms:
-5 + 3.5x + 8x
Combine like terms: 3.5x + 8x = 11.5x
-5 + 11.5x

1) 5.3m + 7m
= 12.3m
2) 47.9w - 31.8w
=16.1w
3) 0.3y + 4.1y + 2.5y
= 4.4y + 2.5y
= 6.9y
4) 27y - 4.7y - 13.8y
= 22.3y - 13.8y
= 8.5y
5) 3.5x - 5 + 8x (<== is the middle one supposed to be -5 and not -5x?)
= 3.5x + 8x - 5
= 11.5x - 5

1. 5.3m + 7m = 12.3m
2. 47.9w - 31.8w = 16.1w
3. 0.3y + 4.1y + 2.5y = 6.9y
4. 27y - 4.7y - 13.8y = 8.5 y
5. 3.5x - 5 + 8x = 11.5x - 5
This is simple addition and subtraction.

Simply add the coefficients of the like terms.
1) (5.3 + 7)m = 12.3m
2) (47.9 - 31.8)w = 16,1w
3) (0.3 + 4.1 + 2.5)y = 6.9y
4) (27 - 4.7 - 13.8)y = 8.5y
5) (3.5 + 8)x - 5 = 11.5x - 5
I think this is clear to you. Good luck.

*Hi-solve according to the operation >
1. 5.3m + 7m = 12.3m
2. 47.9w - 31.8w = 16.1w
*Give the rest a try-I know you can do it :-)

add or subtract like terms.
5.3m+7m=12.3m
47.9w-31.8w=16.1w
0.3y+4.1y+2.5y=6.9y
27y-4.7y-13.8y=8.5y
3.5x-5+8x=13x-5
it is so easy!
