Question

4x+0.1x=1.44

Answer 1

if you dont like the decimal, multiply both sides by 100 to get
\[400x+10x=144\] then work from there

Answer 2

combine like terms to get
\[410x=144\] then divide to get
\[x=\frac{144}{410}\] then maybe reduce

Answer 3

so if the answer is 0.3512 then what would it be if you didnt times the originals by 100 ?
