7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
-15
18y+5y+48+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
V+9/3=8 V=8*3-9 or 15
h = -5 -7 * -5 = 35 A negative times a negative equals a positive.
If: 7h+4 = -80 then h = -12
h = 0.538462 14 + 5h + 2h = 5h + 28h 14 + 7h = 33h 14 + 7h - 7h = 33h - 7h 14 = 26h 14/26 = 26/26h 0..538462 = h
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.

18y+5y+48+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
V+9/3=8 V=8*3-9 or 15
h = -5 -7 * -5 = 35 A negative times a negative equals a positive.
-7h = 35h = -5
7h+39=60 Take away 39 from both sides (called isolating your variable) 7h=21 Divide by seven, because (I assume) you are looking for h, not 7h h=3 And to check: 7(3)+39=60 21+39=60 60=60
18y+48+5y+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
-48
I would not fully go by my answer but I think its h=6
