Answer 1

\(\left(x\times4+x\times6\right):25=42\)

\(\left(x\times4+x\times6\right)=42\times25\)

\(\left(x\times4+x\times6\right)=1050\)

\(x\times\left(4+6\right)=1050\)

\(x\times10=1050\)

\(x=1050:10\)

\(x=105\)

Answer 2

(2x + 10):25= 42

(2x+10)=42×25

(2x+10)=1050

2x=1050-10

2x=1040

=>x=1040:2=520

Answer 3

$\left(x\times 4+x\times 6\right):25=42$

$\left(x\times 4+x\times 6\right)=42\times 25$

$\left(x\times 4+x\times 6\right)=1050$

$x\times \left(4+6\right)=1050$

$x\times 10=1050$

$x=1050:10$

$x=105$
