Question

solve equation quickly ​

Answer 1

2/3x+9=3/4-7

2/3x=3/4-7-9

2/3x=3-28-36/4

2/3x=61/4

x=61/4×2/3

x=61/6

Answer 2

7×2/3x+9=3/4-7

23x+9=3/4-7

23x+9=3/4-7/1

23x+9=3/4-7/4

23x+9=3/4-28/4

23 X+9=-25/4

23x+9+25/4=0

23x=25/4-9/1

23x= 25/4-36/4

23x=-11 /4

X= 23+11/4

x=92+11/4=

X=310/4

x=87.5
