Question

[52÷13×100-5×(180×2-2×m)]÷25=4

Answer 1

[52:13×100-5×(180×2-2×m)]:25=4
[52:13×100-5×(180×2-2×m)]=4×25
[52:13×100-5×(180×2-2×m)]=100
[52:13×100-5×(360-2×m)]=100
[4×100-5×(360-2×m)]=100
[400-5×(360-2×m)]=100
[5×(360-2×m)]=400-100
[5×(360-2×m)]=300
(360-2×m)=300:5
(360-2×m)=60
2×m=360-60
2×m=300
m=300:2
m=150
