Question

resolver essa equação 5(2x+7)-1=4(x-5)+9

Answer 1

5(2x+7)-1=4(x-5)+9
10x + 35 - 1 = 4x -20 + 9
10x - 4x = -20 + 9 - 35 + 1
6x = -45
x = -45/6

Answer 2

5(2x+7)-1=4(x-5)+9

10x+35−1=4x−20+9

10x+34=4x−20+9

10x+34=4x−11

10x+34−4x=−11

6x+34=−11

6x=−11−34

6x=−45

x =  - 45 / 6

x = - 15 /2
