Q. Is b=91 a solution to this equation?20=13bChoices:(A) yes(B) no
Identify Equation: We have the equation 20=13b. Identify the equation after substituting b=91. Substitute 91 for b in 20=13b. Equation: 20=1391
Substitute and Simplify: Simplify 91/13. 91 divided by 13 equals 7. 91/13=7
Check Solution: We found: 1391=7Is b=91 a solution to the equation 20=13b?For b=91, the equation becomes 7=20, which is not true.So, b=91 is not a solution to the equation 20=13b.
