8(m-5)=2(3m-8)
8m-40=6m-16
8m-40-6m+16=0
2m-24=0
2m=24
m=12

8(m-5)=2(3m-8)................
distribute it.... 8m-40=6m-16
subtrract 6m on both sides...... 2m-40=-16
add 40 on both sides....... 2m=24
divide by 2 on both sies..... m=12

8(m-5)=2(3m-8)
8m-40=6m-16
2m-40=-16
2m=24
m=12
Check:
8(12-5)=2(3(12)-8)
8(7)=2(36-8)
8(7)=2(28)
56=56
