The solution is 0

Work Step by Step

12+5t =6(t+2) Apply the distributive property 12+5t=6t+12 Subtract 12 from both sides 12+5t-12=6t+12 -12 Simplify 5t=6t Subtract 6t from both sides 5t-6t=6t-6t -t=0 Divide by -1 on both sides $\frac{-t}{-1}$=$\frac{0}{1}$ t=0 The solution is 0 Check 12+5t =6(t+2) Replace t with 0 12+5$\times$0=6(0+2) 12+0=6$\times$2 12=12
