71 + 65 x 4 = x + 140/x + 260
x + 140/x + 260 = 71+ 65 x4
x + 140/x + 260 = 71 + 260
x + 140/x = 71
x/x + 140/x = 71
140/x = 71 - 1
140/x = 70
x = 140 : 70
x = 2
Tìm x
71 + 65 x 4 = \(\frac{x+140}{x}+260\)
tìm X
71 + 65 x 4 = X + 140 / X +260
Tìm \(x\)
\(71+65\)x 4= \(\frac{x+140}{x}\)+ 260
71 + 65 x 4 \(=\frac{x+140}{x}+260\)
tìm x: \(71+65\cdot4=\frac{x+140}{x}+260\)
tìm x
( x * 0,25 + 1999 ) * 2000 = ( 53 + 1999 ) * 2000
71 + 65 * 4 = \(\frac{x+140}{x}\) + 260
Tìm x:
a) (X x 0,25 + 1999) x 2000 = ( 53 + 1999 ) x 2000
b) 71 + 65 x 4 = \(\dfrac{x+140}{x}\) + 260
Tìm x biết \(71+65\times4=\frac{x+140}{x+260}\)
71 + 65 x 4 = x + 140 / x + 260.
