Question

SOLVE 7.1=-2X-4.1(3+2.4X)

Answer 1

7.1=-2X-4.1(3+2.4X) is the same has

7/10=-2x-[3+(24)/10]4/10
you know that right
?

Answer 2

and then you factorize the 10's like this:

7/10=={-20x-[3+4(24)/10]}/10 \[\frac{ a }{ c }=\frac{ b }{ c }\rightarrow a=b\]

Answer 3

sorry my bad
7/10=={4[-2x-[3+(24)/10]]}/10

and then 7=-8x-4[3+(24)]/10

so -8x-(12+96)/10=7
-8x=7+(12+96)10
-8x=7+(108)/10
-8x=(70+108)/10
-8x=(178)/10
x=(178)/(10*8)
x=178/80
x=2.225
