tim x biet : x . (x 2)= 35
Tim x;y biet (x+y+5)^2+(x*y+35)^2=0
tim x, biet; 35 x=7 x+16
tim x ,biet ;
35 + X x 12 = 83
.35 + x . 12 = 83..............................
=> 12x = 48............................................
=> x = 4...............................................
.35 + x . 12 = 83..............................
=> 12x = 48............................................
=> x = 4...............................................
.35 + x . 12 = 83..............................
=> 12x = 48............................................
=> x = 4...............................................
Tim X biet : ( 1/15 + 1/35 + 1/63 ) x X = 1
tim so tu nhien x biet: (x - 35) - 120 = 0
tim x,biet
a)x-6=35:7+42:6
b)x-54:27=42-26:2
c)36:x+81:x=130:10
a. x -6 = 35 : 7 + 42 : 6
=> x - 6 = 5 + 7
=> x -6 = 12
=> x = 12 + 6
=> x = 18
Các câu sau tương tự, bạn học tốt nha! .-.
a)x-6=5+7
x-6=12
x=6.
b)x-2=42-13
x-2=29
x=29+2
x=31
c)(36+81):x=13
117:x=13
x=117:13
x=9.
a)x-6=35:7+42:6
x-6=5+7
x-6=12
x=12:6
x=2
Vậy x=2
tim x biet 3x=5y+35
pt vô số nghiệm \(\left(x;y\right)=\left(x;\frac{3x-35}{5}\right)\)
TIM x , biet
12 nhan X - 54 : 52 = 35
\(12.x-5^4\div5^2=35\)
\(12.x-5^2=35\)
\(12.x-25=35\)
\(12.x=60\)
\(x=60\div12\)
\(x=5\)
Ta có:
\(12\times x-5^4:5^2=35\)
\(\Leftrightarrow12\times x-5^{4-2}=35\)
\(\Leftrightarrow12\times x-5^2=35\)
\(\Leftrightarrow12\times x-25=35\)
\(\Leftrightarrow12\times x=35+25\)
\(\Leftrightarrow12\times x=60\)
\(\Leftrightarrow x=60\div12\)
\(\Leftrightarrow x=5\)
