Question

a : 2 + a : 4 + a : 3 + 2890 = 3528

Answer 1

a : 2 + a : 4 + a : 3 + 2890 = 3528

a:(2+4+3)+2890=3528

a:(2+4+3)=3528-2890

a:9=638

a=638*9

a=5742

Answer 2

x=\(\frac{7656}{13}\)

Answer 3

a : 2 + a : 4 + a : 3 + 2890 = 3528

a:(2+4+3)+2890=3528

a:(2+4+3)=3528-2890

a:9=638

a=638*9

a=5742

 

Answer 4

x = 7656/13 nhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 5

=>a:2+a:3+a:4=3528-2890=638

\(\Rightarrow\frac{a}{2}+\frac{a}{3}+\frac{a}{4}=638\Rightarrow\frac{6a}{12}+\frac{4a}{12}+\frac{3a}{12}=638\Rightarrow\frac{6a+4a+3a}{12}=638\)

=>13a=638.12=7656

=>a=7656:13

=>a=7656/13
