Answer:
(12, -23)
Step-by-step explanation:
to find x, substitute the value of y into y
-2x+1=-3x+13
collecting like terms
-2x+3x=13-1
x=12
to find y substitute the value x=12 into any of the equation
y=-3x+13
y=-3(12) +13
y= -36+13
y=-23
Anya's current age is 30 years and Cole current age is 27 years
Let x represent Anya current age and y represent Cole current age.
Anya is three years older than her brother, Cole. Hence:
x = y + 3
x - y = 3 (1)
In 11 years, the sum of their ages will be 79. Hence:
(x + 11) + (y + 11) = 79
x + y = 57 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 27
Anya's current age is 30 years and Cole current age is 27 years
