Question

8(15x + 3) = 5(20x + 12) – 16 Resuelva las ecuaciones: 6(5x – 3) – 9(3x – 2) = 40 – 2x

Answer 1

Explicación paso a paso:

8(15x+3) = 5(20x+12)-16

120x+24 = 100x+60-16

120x-100x = 60-16-24

20x = 20

X = 20/20

X = 1

6(5x-3)-9(3x-2) = 40-2x

30x-18-27x+18 = 40-2x

3x = 40-2x

3x+2x = 40

5x = 40

X = 40/5

X = 8
