Question

\(\frac{x+140}{x}\)+260+=21+65x4

Answer 1

\(\frac{x+140}{x}+260=21+65×4\)

\(\frac{x+140}{x}+260=21+260\)

\(\frac{x+140}{x}=21\)

\(\left(x+140\right):x=21\)

 x + 140=21× x

140= 21× X - X

140=  21×X-X×1

140=(21-1)×X

140=20×X

X=140:20

X=7

Answer 2

\(\left(x+140\right):x+260=21+260\)

\(\left(x+140\right):x=281-260\)

\(\left(x+140\right):x=21\)

\(x+140=21\times x\)

\(21\times x-x=140\)

\(20\times x=140\)

\(x=7\)

Answer 3

\(\frac{x+140}{x}+260=21+65\times4\)

\(\Rightarrow\frac{x}{x}+\frac{140}{x}+260=281\)

\(1+\frac{140}{x}+260=281\)

\(261+\frac{140}{x}=281\)

\(\frac{140}{x}=281-261\)

140/x = 20

x = 140 : 20

x = 7
