Question

Va rog faceți c d e f și g de la 7

Answer 1

c) 51627-x=26339-10
51627-x=26329
x=51627-26329
x=25298
d) (8264-x)-4337=2983
8264-x=2983+4337
8264-×=7320
x=8264-7320
x=944
e) (5*x)+816+707×101=63468
(5*x )+816+71407=63468
5*x+72223=63468
5*x=72223-63468
5*x=8755
x=8755÷5
x=1751
f) 21-x÷[9371-10*(1288-351)]=20
21-x÷[9371-10*937]=20
21-x÷[9371-9370]=20
21-x÷1=20
×=21*1-20
x=1
g) [x+4*4+4]÷4+16+4=29
x+16+4÷4+20=29
x+16+1=29-20
x+17=9
x=17-9
x=8.
