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

Mathematics

Oxana [17]3 years ago

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.

9x - 4/x = 3. How to solve this? What is the value of x?
Ket [755]
9x-4/x=3 ok first lets get the like terms together! So 9x+1x=10x rewrite 10x-4=3 add 4 to both sides 10x=7 then divide 10 7/10=.7 x=.7
Or you can do it this way
9x-4/x=3 combine like terms so times -4 to both sides 3*-4=-12 rewrite 9x+x=-12 combine like term (still got some) 9x+1x=10x rewrite 10x=-12 divide 10 to both sides -12/10=-1.2 rewrite x=-1.2 (I'm like 95% sure it's this one) hope this helps!!! Have a nice nite (Don't be afraid to ask me about details on this or another question)!!!
