Question

Eva is 8 years younger than Leo. The sum of their age is 34. Define a variable. Then write and solve an equation to find Eva's and Leo's ages.

Answer 1

If eva's age is x and leo's age is y, x+8=y and x+y=34. Substituting x+8 for y, x+x+8=34 and subtracting 8 from both sides, we get that 2x=26 and x=13
