Answer: 1. [tex]t=18[/tex]
2. [tex]b=-1[/tex]
Step-by-step explanation:
1. The given equation: [tex]5 + t = 23[/tex]
To find t , we subtract 5 from both sides , we get
[tex]t=23-5=18[/tex]
Hence, the solution of the equation is [tex]t=18[/tex]
2. The given equation: [tex]-7 + b = -8[/tex]
To find b , we add 7 on both the sides, we get
[tex]b=-8+7=-(8-7)=-1[/tex]
Hence, the solution of the equation is [tex]b=-1[/tex]
