Subtract the second term from the first term.

21. -841a, -97a
22. 9124x, 826x
23. -174bc, 526bc
24. -47xyz, -62xyz
25. -206ab, 168ab
26. 325a², 512a²
27. -38.6pr, 10.94pr
28. -947mn, -718mn
29. 716xy, 369xy
30. -4817mnx, -5724mnx

To solve these subtraction problems involving algebraic terms, we need to subtract the coefficients of the given like terms. Let's go through each problem step-by-step:

Subtract − 97 a from − 841 a :
− 841 a − ( − 97 a ) = − 841 a + 97 a = − 744 a

Subtract 826 x from 9124 x :
9124 x − 826 x = 8298 x

Subtract 526 b c from − 174 b c :
− 174 b c − 526 b c = − 700 b c

Subtract − 62 x yz from − 47 x yz :
− 47 x yz − ( − 62 x yz ) = − 47 x yz + 62 x yz = 15 x yz

Subtract 168 ab from − 206 ab :
− 206 ab − 168 ab = − 374 ab

Subtract 512 a 2 from 325 a 2 :
325 a 2 − 512 a 2 = − 187 a 2

Subtract 10.94 p r from − 38.6 p r :
− 38.6 p r − 10.94 p r = − 49.54 p r

Subtract − 718 mn from − 947 mn :
− 947 mn − ( − 718 mn ) = − 947 mn + 718 mn = − 229 mn

Subtract 369 x y from 716 x y :
716 x y − 369 x y = 347 x y

Subtract − 5724 mn x from − 4817 mn x :


\[-4817mnx - (-5724mnx) = -4817mnx + 5724mnx = 907mnx\]

These problems require careful manipulation of negative and positive terms to ensure accurate subtraction. Practice with this type of problem helps in understanding how to work with algebraic expressions and coefficients.
