Question

0.4x-0.8(x-4) =1.3x - 1.9how do I solve it?​

Answer 1

Answer:

x = 3

Step-by-step explanation:

First, multiply all four terms by 10 to eliminate the fractions:

4x - 8(x-4) = 13x - 19

Next, carry out the indicated multiplication, obtaining:

4x - 8x + 32 = 13x - 19

Combining the x terms, we get:

-4x + 32 = 13x - 19, or

        32 = 17x - 19

Combining the constants, we get 51 = 17x, and so x = 51/17 = 3.
