Answer :
Answer:
Step-by-step explanation:
4(x+5)=9x+4x-34
4x + 4*5 = 9x + 4x - 34 {distributive property}
4x + 20 - 4x = 9x + 4x - 34 - 4x {subtraction property of equality}
20 = 9x - 34
20 + 34 = 9x - 34 + 34 {Addition property of equality}
54 = 9x
54/9 = 9x/9 {division property of equality}
6 = x
x = 6
