Answer:
37/40

1) +
2) Have a common denominator
So, multiply 3/10 by 4/4 and multiply 5/8 by 5/5
3) Now, you have
4) 12 + 25 = 37 and you keep the denominator 40 since they're the same on both fractions.
5 ) 37/40
Step-by-step explanation:
4(x – 3) = 20
1st Step: 4x – 12 = 20
Reason: Distribute
2nd Step: 4x – 12 + 12 = 20 + 12
» 4x = 32
Reason: Add 12 to both sides
3rd Step: 4x ÷ 4 = 32 ÷ 4
» x = 8
Reason: Divide both sides by 4
