cac ae giup mk giai bai nay vs
cac ban giai giup mk bai toan tim x nay nha 3 . ( 5x + 15 ) + x - 11 = 98
3 . ( 5x + 15 ) + x - 11 = 98
=>3(5x+15)+x=109
=>15x+45+x=109
=>16x=64
=>x=4
cac ban giup mk bai nay vs...
tim x:
x/7=x+16/35
8/x=7/x-16
\(\frac{x}{7}=\frac{x+16}{35}\)
\(\Leftrightarrow x\cdot35=7\left(x+16\right)\)
\(\Leftrightarrow35x=7x+112\)
\(\Leftrightarrow35x-7x=112\)
\(\Leftrightarrow28x=112\)
\(\Leftrightarrow x=4\)
Vậy x = 4
\(\frac{8}{x}=\frac{7}{x-16}\)
\(\Leftrightarrow8\left(x-16\right)=x\cdot7\)
\(\Leftrightarrow8x-128=7x\)
\(\Leftrightarrow8x-7x=128\)
\(\Leftrightarrow x=128\)
Vậy x = 128
a,\(\frac{x}{7}=\frac{x+16}{35}< =>\frac{5x}{35}=\frac{x+16}{35}\)
\(< =>5x=x+16\)
\(< =>4x=16< =>x=4\)
b,\(\frac{8}{x}=\frac{7}{x-16}\)\(< =>8x-128=7x\)
\(< =>x=128\)
