x + 9x + 7x + 5x = 2244
Tìm x, biết:
x+ 9x + 7x + 5x= 2244
Các bạn giải giúp mình:
5^2x-3-2x5^2=5^2x3 (^ là mũ)
x+9x+7x+5x=2244
Tìm x:
x + 9x + 7x + 5x =8844
Tìm x biết 2+ 3x + 5x + 7x + 9x + ... + 99x = 7500
x+2x+3x+3x+4x+5x+6x+7x+8x+9x+10x=-165.tim x
x.1x.2x.3x.4x.5x.6x.7x.8x.9x.10x.11x=5500
x=?
a) 4(x+3)-(2x-12)=x-(-11+4)
b) -(4x-13)+(5x-4)= -3-(-15+7)
c) (5x-3)-(-2x+4)=6x-12
d) (15x+20)-(9x-3)=5x-(-12)
e) (7x+14)+(3x-8)= -(-9x+3)
giúp mình nha.................
6x=3x+1-5x+6x-5x+4x-9x+7x
