Tìm x biết:
a) 4(18-5x) - 12(3x-7) = 15(2x-16) - 6(x+14)
b) 5(3x+5) - 4(2x-3) = 5x+3(2x+12)+1
c)2(5x-8) - 3(4x-5) = 4(3x-4) + 11
d) 5x-3 {4x-2 [4x-3(5x-2)]}=182
Tìm x
\(\frac{2x+2}{5x-3}=\frac{2x+12}{5x+18}\)
Tìm x biết :
a, 4.(18 - 5x) - 12.(3x - 7) = 15.(2x - 16) - 6(x + 14)
b, 5.(3x + 5) - 4.(2x - 3) = 5x + 3.(2x + 12) + 1
c, 2.(5x - 8) - 3.(4x - 5) = 4.(3x - 4) + 11
d, (3x + 2)(2x + 9) - (x + 2)(6x + 1) = (x + 1) - (x - 6)
e, (8x - 3)(3x + 2) - (4x + 7)(x + 4)= (2x + 1)(5x - 1) - 33
Giá trị x thỏa mãn 2x + 2/ 5x - 3 = 2x + 12/ 5x + 18
Giá trị x thỏa mãn 2x + 2/ 5x - 3 = 2x + 12/ 5x + 18
Tìm x:
\(\frac{2x+2}{5x-3}=\frac{2x+12}{5+18}\)
(2x+2):(5x+3)=(2x+12):(5x+18)
Tim x biet:
\(\frac{2x+2}{5x-3}=\frac{2x+12}{5x+18}\)
tim x trong tỉ lệ thức sau: 2x+2/5x-3=2x+12/5x+18
