Answer:
65 years old
Step-by-step explanation:
G . = grandma
d = grand daughter
g = 13d
g+1= 11(d+1) - - distributive property
g + 1 = 11d+11
subtract 1 from both sides
g = 11d+10
substitute g = 13d into equation
13d = 11d+10
subtract 11d from both sides
2d = 10
divide both sides by 2
d = 5. the grandaughter is 5, and the grandma is currently 13 * the granddaughters age. 5*13 = 65. hope it helped
