Answer:
18x+36
Step-by-step explanation:
1. Simplify \frac{4}{5}(30x-40)54(30x−40) to \frac{4(30x-40)}{5}54(30x−40).
-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4
2. Factor out the common term 1010.
-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4
3. Simplify 4\times 10(3x-4)4×10(3x−4) to 40(3x-4)40(3x−4).
-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4
4. Simplify \frac{40(3x-4)}{5}540(3x−4) to 8(3x-4)8(3x−4).
-8(3x-4)+42x+4−8(3x−4)+42x+4
5. Expand by distributing terms.
-(24x-32)+42x+4−(24x−32)+42x+4
6. Remove parentheses.
-24x+32+42x+4−24x+32+42x+4
7. Collect like terms.
(-24x+42x)+(32+4)(−24x+42x)+(32+4)
8. Simplify.
18x+3618x+36
