please help

for the first one just substitute y=2
OK i got that one
for the second one just draw up a table with x-values from 1 to 5 then substitute each x-value into 5x+3
|dw:1444766775285:dw|
for the 3rd just substitute x=1/2 into each equation until you find the one that's valid
what the hell is that?
|dw:1444766775285:dw|
2. 5x + 3 = 23 |dw:1444799978107:dw| THEREFORE ,x= 4 is the solution of the above equation
