Question

a+(8×5)=6×7+36:4
(8×4)+a=6×9+16:2
b+(5×5)=63:9+4×7
a-(9×8)=(32:4)+225
c-(6×3)=126+(7×5)+27:3
(7×8)-d=92-10×5​

Answer 1

a+(8×5)=6×7+36:4

a+40=42+9

a+40=51

a=51-40

a=11

(8×4)+a=6×9+16:2

32+a=54+8

32+a=62

a=62-32

a=30

b+(5×5)=63:9+4×7

b+25=7+28

b+25=35

b=35-25

b=10

a-(9×8)=(32:4)+225

a-72=8+225

a-72=233

a=233+72

a=305

c-(6×3)=126+(7×5)+27:3

c-18=126+35+9

c-18=170

c=170+18

c=188

(7×8)-d=92-10×5

56-d=92-50

56-d=42

d=56-42

d=14
