Question

Giúp nhanh v

Answer 1

a, \(2x=55\Leftrightarrow x=\dfrac{55}{2}\)

b, \(x=100-150=-50\)

c, \(x+33=71-26=45\Leftrightarrow x=45-33=12\)

d, \(x+73=102\Leftrightarrow x=102-73=29\)

e, \(x+41=100\Leftrightarrow x=100-41=59\)

f, => x - 9 = 0 <=> x = 9 

g, => x - 1 = 1 <=> x = 2 

h, \(2^x=2^5\Rightarrow x=5\)

Answer 2

2x=55⇔x=5522x=55⇔x=552

b, $x=100-150=-50$

c, $x+33=71-26=45\iff x=45-33=12$

d, $x+73=102\iff x=102-73=29$

e, $x+41=100\iff x=100-41=59$

f, => x - 9 = 0 <=> x = 9 

g, => x - 1 = 1 <=> x = 2 

h, ${}^{}={}^{}\Rightarrow x=5$
