22(x+32)-5=55
155-10(x+1)=55
5.22+(x+3)=52
53-5(4+x)=15
a/ 22(x + 32) - 5 = 55 b/ 155 - 10(x+1) = 55
4(x + 32) = 60 10(x + 1) = 100
x + 32 = 60 : 4 x + 1 = 10
x + 32 = 15 x = 10 - 1
x = 15 - 32 x = 9
x = - 17
c/ 5. 22 + (x+3) = 52 53 - 5 (4 + x) = 15
20 + (x+3) = 25 125 - 5(4 +x) = 15
x+ 3 = 5 5(4 + x) = 110
x = 5-3 4 + x= 110 : 2
x = 2 4 + x = 55
x = 51
ủng hộ mk nha !!!! ^_^

A. { [ ( 32 + 1 ) . 10 - ( 8 : 2 + 6 ) ] : 2 } +55 - ( 10 : 5 ) 3
B. { [ ( 10 - 2 . 3 ) . 5 ] + 2 - 2 . 6 } : 2 + ( 4 .5 )2
Bài làm :
\(A.\left\{\left[\left(3^2+1\right).10-\left(8:2+6\right)\right]:2\right\}+55-\left(10:5\right)^3\)
\(=\left\{\left[10.10-\left(4+6\right)\right]:2\right\}+55-\left(10:5\right)^3\)
\(=\left[\left(100-10\right):2\right]+55-2^3\)
\(=\left(90:2\right)+55-8\)
\(=45+55-8\)
\(=92\)
\(B.\left\{\left[\left(10-2.3\right).5\right]+2-2.6\right\}:2+\left(4.5\right)^2\)
\(=\left\{\left[\left(10-6\right).5\right]+2-12\right\}:2+20^2\)
\(=\left[\left(4.5\right)+2-12\right]:2+400\)
\(=\left(20+2-12\right):2+400\)
\(=10:2+400\)
\(=5+400\)
\(=405\)
Học tốt nhé
a) {[(32 + 1).10 - (8:2 + 6)] : 2} + 55 - (10 : 5)3
= {[(9 + 1).10 - (4 + 6)] : 2} + 55 - 23
= {[10.10 - 10] : 2} + 55 - 23
= {[10(10 - 1)] : 2} + 55 - 8
= {[10.9] : 2} + 55 - 8
= 45 + 55 - 8 = 92
b) {[(10 - 2.3).5] + 2 - 2.6} : 2 + (4.5)2
= {[(10 - 6).5] + 2 - 12} : 2 + 202
= {[4 . 5] + 2 - 12} : 2 + 400
= {20 + 2 - 12} : 2 + 400
= 10 : 2 + 400 = 5 + 400 = 405
\(A=\left\{\left[\left(3^2+1\right)10-\left(8:2+6\right)\right]:2\right\}+55-\left(10:5\right)^3\)
\(A=\left[\left(100-10\right)\frac{1}{2}\right]+55-8\)
\(A=45+55-8=92\)
\(B=\left\{\left[\left(10-2.3\right).5\right]+2-2.6\right\}:2+\left(4.5\right)^2\)
\(B=\left(20+2-12\right):2+400\)
\(B=405\)
