Question

0.6(4x-12)-0.4(5x-7)

Answer 1

0.6 * (4x - 12) - 0.4 * (5x - 7) = 0.4x  - 7.2 - 2x + 2.8 = -1.6x - 4.4 = - (1.6x + 4.4) 

Answer 2

2,4x-7,2-2x+2,8=0
0,4x-4,4=0
0,4x=4,4
x=11

Answer 3

Let's simplify the expression step by step:

0.6(4x-12)-0.4(5x-7)

= 2.4x - 7.2 - 2x + 1.4 // Distribute the coefficients

= 0.4x - 5.8 // Combine like terms

Therefore, the simplified expression is 0.4x - 5.8.
