Question

розвяжить ривняння 3/4(1/2x+2/3)=3x+2 1/4

Answer 1

3/4(1/2х+2/3)=3х+2 1/4
3/8х+1/2=3х+2 1/4
3/8х-3х=2 1/4-1/2
-2 5/8 х=1 5/4-2/4
-2 5/8 х=1 3/4
х=7/4:(-21/8)
х=-2/3

Answer 2

3/4( 1/2 х+2/3)=3х+2 1/4
3/8 х+1/2=3х+2 1/4
3х - 3/8 х=1/2 - 2 1/4
2 5/8 х=2/4 - 2 1/4
21/8 х= -1 3/4
х= -7/4 :21/8
х= - 7/4 * 8/21
х= - 2/3
