-7y=6;if y=13, we have -7%2A13=6=> -91=6 which is not true (-91%3C%3E6 )

3a-1=4;if a=%285%2F3%29 we have cross%283%29%285%2Fcross%283%29%29-1=4=>5-1=4
=>4=4 which is true


2%28b-3%29+=+-2+%282-3b%29; if b=-4 we have 2%28-4-3%29+=+-2+%282-3%28-4%29%29=>2%28-7%29+=+-2+%282%2B12%29=>-14+=+-2+%2814%29=>-14+=+-28 which is not true

5x-2=0%2F8; =>5x-2=0
if x=%282%2F5%29 we have cross%285%29%282%2Fcross%285%29%29-2=0=>2-2=0=>0=0 which is true

6%28t%2B2%29=3%287-t%29; if t=-1 we have 6%28-1%2B2%29=3%287-%28-1%29%29=>6%281%29=3%287%2B1%29=>6=3%288%29=>6=24 which is not true

Determine if the given value for each variable is a solution set for the equation shown
-7y=6;y=13
No:: y = -6/7
----------------------
3a-1=4;a=5/3
a = 5/3; yes
--------------

2(b-3) = -2 (2-3b); b=-4
2b-6 = -4+6b
4b = -2
b = -1/2
----------------------
5×-2=0/8;x=2/5
x = 2/5
-----------------

6 (t+2)=3 (7-t);t=-1
6t+12 = 21-3t
9t = 9
t = 1
