Tim x biet 11*(x-6)=4x+11
Tìm x biết:
a/2+4+6+8+...+2x=210
b/11(x-6)=4x+11
c/(4x-8).[x+(-3)] =0
1) tìm x
a) 11.(x-6)=4x+11
b) |x-3|+1=x
Tìm x:
a,11(x-6)=4x+11
b,\(\frac{6}{8}\)=\(\frac{15}{x}\)
giải đầy đủ giùm mk nha!(^_^)
Tìm x: 11.(x-6)=4x+11
(3x+0,8):x+14,5=15
Tìm x , y biết
a ) x mũ 2 = x mũ 5
b ) ( 3x - 12 )mũ 15 = ( x - 17)mũ 15
c ) ( 4x - 16 )mũ 15 - ( x - 2 )mũ 15 = 0
d ) ( x - 3 )mũ 11 = ( 2x - 6 )mũ 11
tìm x
25.3 - 3.(x+1)=42
(4x + 5) : 3 - 112:11=22
3x - 15 . 4 = 6.(19 - x)
(x - 7).(2x - 16)=0
tìm x
149- ( 35:x + 3 ) . 17 = 13
121:11-(4x+5 ) : 3 = 4
2+4+6+8+....+x = 2450
1x32+7x8+4x = 200x
tìm x biết
a,121:11- (4x+5):3=4
b,2+4+6+....+x=2450
