Answer 1

1. (9×9-6×6-a)+(13+17×1)=5×10+3=
(81-36-a)+(13+17)=50+3=
a=45+30-53=
a=85- 53
a=32

2.(99-b-3×8)+2×3=8×2+5×10=
b=(99-24)+6-16+50=
b=75+6+66=
b=81+66=
b=147

3.(6×4+c)-6×4=2×2=
c=24-24+4=
c=0+4=
c=4

4.(2×3+d)-(7×9+6)=7×7=
d=6-(23+6)+49=
d=6-29+49=
d=23+49=
d=73

5.(e-5×6+10×5)-50+4×8=42
(e-30+50)-50+32-42=
e=80-82-42
e=80-40
e=40

6.(96-3×4-5×8)+f-9×7=13
f=(93-12-40)-23+13=
f=(81-40)-36=
f=41-36=
f=5

7.(23-6×4+g)+3×9-8×3-28=34
g=(23-24)+27-24-28+34=
g=1+2-28+34=
g=3-62=
g=59

8.(3×9+7×h-53)+5×2-(12-4×2)=6×6
h=(27+7×53)+10-(9×2)-36=
h=(27+371)+10-18-36=
h=398+10-18-36=
h=408-18-36=
h=390-36=
h=354

9.8×8-32-(6×i-51)-(40-3×10)=3×3
i=64-42-(6×51)-(40-30)-9=
i=22-306-10-9=
i=284-10-9=
i=274-9=
i=265
