tìm x
\(a,\frac{3}{7}x-\frac{1}{35}=\frac{3}{5}\)
\(b,1,5-x:\frac{1}{2}=\frac{1}{4}\)
\(c,3x-5=7\left(2x-1\right)+3\)
\(d,7-\left|3x-1\right|=\frac{1}{2}\)
help me !!các bạn giúp mk với
Tìm x:
a) \(\frac{1}{4}+\frac{1}{3}:\left(2x-1\right)=-5\)
b) \(-\left(5\frac{3}{8}+x-7\frac{5}{24}\right):2019\frac{11}{37}=0\)
Help me!!!
Tìm số nguyên x biết:
a)\(9-25=\left(7-x\right)-\left(25+7\right)\)
b)35 - 3 . I x I=5.(23-4)
c)10+2.I x I = 2.(32-1)
\(\dfrac{1}{5}\).\(\left(x+\dfrac{1}{5}\right)\)\(+\)\(\dfrac{2}{5}\)\(\left(x+\dfrac{5}{3}\right)\)\(=\)\(\dfrac{98}{75}\)
help me please :D
1)\(4\left(x-5\right)-3\left(x+7\right)=-19\)
2)\(7\left(x-3\right)-5\left(3-x\right)=11x-5\)
3)\(4\left(2-x\right)+4\left(x-3\right)=14\)
4)\(-5\left(2-x\right)+4\left(x-3\right)=10x-15\)
5)\(7\left(x-9\right)-5\left(6-x\right)=-5+11x\)
6)\(-7\left(3x-5\right)+2\left(7x-14\right)=28\)
7)\(4\left(x-5\right)-3\left(x+7\right)=5.\left(-4\right)\)
a,\(\left(-5\right)^x.5^4=\left(-5\right)^7\)
b,\(25^x:5^{10}=5^{12}\)
c,\(9^x:27^5=3^{17}\)
d,\(\left(-2\right)^{18}.2^{x+1}=2^{43}\)
