Show work and help PLEASE 5 6 7 and 8 please

-10y+18=-3(5y-7)+5y do the parenthasees first -10y+18=-15y+21+5y group like terms (y with y and numbers with numbers)

-10y+18=-10y+21 add 10y to both sides and you get 18=21 which is false so no solution

8(t+2)-3(t-4)=6(t-7)+8 do the parenthasees 8t+16-3t+12=6t-42+8 group like terms 5t+28=6t-36 subtract 5t from both sides 28=t-36 add 36 to both sides 64=t

do the parenthasees first 20+8x-5=9x+21 add like terms 15+8x=9x+21 subtract 8x from both sids 15=x+21 subtract 21 from both sides x=-6

distribute the parenthasees 12x-48+3=15 add like terms 12x-45=15 add 45 to both sides 12x=60 divide both sides by 12 x=5

In problem 5, there is no solution. In problem 6, the solution is t = 62 . In problem 7, the solution is x = − 6 and in problem 8, the solution is x = 5 .
