25+(x-5)=-415-(15-415)
25+(x-5)=-415-(15-415)
25 - (x + 5) = -415 - (15 - 415)
\(25-\left(x+5\right)=-15\)
\(x+5=40\)
\(=>x=35\)
25-(x+5)=-415-15+415
25-(x+5)=(-5)
X+5=25-(-5)
X+5=30
X=30-5
X=25
Vậy x=25
25+(x-5)=-415-(15-415)
25+(x-5)=-415-(-400)
25+(x-5)=-415+400
25+(x-5)=-15
x-5=-15-25
x-5=-40
x=-40+5
x=-35
25+ (x- 5) 415- (15- 415)
25 + ( x - 5 ) = -415 - ( 15 - 415 ) giúp tui zới
\(25+\left(x-5\right)=-15\\ x-5=\left(-15\right)-25=\left(-40\right)\\ x=\left(-40\right)+5=-35\)
25 + (x-5) = -415 - (-400)
25 + (x-5) = -15
x-5 =-15 - 25
x-5 = -40
x = -40 + 5
x = -35
tìm x
a, |x+3| -12 = |-5|
b, 25 - (x-5) = 415 x (15 - 415 )
a, | x + 3 | - 12 = | -5 |
x + 3 - 12 = 5
x + 3 = 5 + 12
x + 3 = 17
x = 17 - 3 = 14
b, 25 - ( x- 5 ) = 415 x ( 15 - 415 )
25 - ( x - 5 ) = 415 x ( - 400 )
25 - ( x - 5 ) = - 166000
x - 5 = 25 - ( - 166000)
x - 5 = 166025
x = 166025 + 5
x = 166030
CHÚC BẠN HỌC TỐT
25 - (x + 5) = -415 - (15 - 415 )
giúp mik vs mik rối quá trời
25-(x+5)= -415 - (15 - 415)
<=> 25 - x - 5 = -415 - 15 + 415
<=> -x = -415 -15 + 415 - 25
<=> -x = -40
<=> x = 40
k ghi lại đề nha :>
\(25-x-5=415-\left(-400\right)\))
20 - x = -415 + 400
20 - x = -15
-x = -15 - 20
-x = -35
x = 35
\(25-\left(x+5\right)=-415-\left(15-415\right)\)
\(\Leftrightarrow\)\(25-\left(x+5\right)=-415-\left(-400\right)\)
\(\Leftrightarrow\)\(25-\left(x+5\right)=-415+400\)
\(\Leftrightarrow\)\(25-\left(x+5\right)=-15\)
\(\Leftrightarrow\)\(\left(x+5\right)=25-\left(-15\right)\)
\(\Leftrightarrow\)\(\left(x+5\right)=25+15\)
\(\Leftrightarrow\)\(x+5=40\)
\(\Leftrightarrow\)\(x=40-5\)
\(\Leftrightarrow\)\(x=35\)
25 - ( x + 5 ) = - 415 - ( 15 - 415 )
Ai làm nhanh đúng mình tick cho nha!!!
a.484+x=(-632)+(-548)
b.(-x)+(-62)+(-46)=-14
c.25+(x-5)=-415-(15-415)
\(a)484+x=\left(-632\right)+\left(-548\right)\)
\(484+x=-1180\)
\(x=(-1180)-484\)
\(x=-1664\)
\(b)\left(-x\right)+\left(-62\right)+\left(-46\right)=-14\)
\(\left(-x\right)+\left(-62\right)=-14-\left(-46\right)\)
\(\left(-x\right)+\left(-62\right)=-14+46\)
\(\left(-x\right)+\left(-62\right)=32\)
\(\left(-x\right)=32-\left(-62\right)\)
\(\left(-x\right)=32+62\)
\(\left(-x\right)=94\)
\(\Rightarrow x=94\)
\(c)25+\left(x-5\right)=-415-\left(15-415\right)\)
\(25+\left(x-5\right)=-415-\left(-400\right)\)
\(25+\left(x-5\right)=-415+400\)
\(25+\left(x-5\right)=-15\)
\(x-5=-15-25\)
\(x-5=-40\)
\(x=-40+5\)
\(x=-35\)
thank you @lê thị thanh huyền
