Answer 1

(2×3+5×i)-3×2=4×5
(6+5×i)-6=20
6+5×i-6=20
5×i=20
i=20÷5=4

a×4-15=(80-75)×5
a×4-15=5×5
a×4=25+15
a×4=40
a=40÷4=10

(6×4-i×3)+9×4=3×10+3×3
24-i×3+36=30+9
24-i×3+36=39
24-i×3=39-36
24-i×3=3
i×3=24-3
i=21÷3=7

96-(8×4+a×3)=5×6+19
96-(32+a×3)=30+19
96-(32+a×3=49
32+a×3=96-49
32+a×3=47
a×3=47-32
a×3=15
a=15÷3=5
