Answer:
jasmine is 39, her sister is 22
Step-by-step explanation:
let j be jasmine's age and s be her sister's age. we can set up these two formulas:
2s - 5 = j
j + s = 61
replace j in the second formula with 2s - 5:
2s - 5 + s = 61
simplify: 3s - 5 = 61
add 5 to each side: 3s = 66
divide each side by 3: s = 22
now replace s with 22 in the first formula:
2(22) - 5 = j
multiply: 44 - 5 = j
subtract: 39 = j
