Explanation:
Let
x
=
the daughter's age
Mrs. Wang is
23
years older, so her age is
x
+
23
In five years, the daughter will be
x
+
5
years old
In five years, Mrs. Wang will be
x
+
23
+
5
=
x
+
28
years old
And, in five years the sum of their ages will be 63, so...
x
+
5
+
x
+
28
=
63
Combine like terms

Answer:
the line with go from the y-intercept -10 to the x-intercept 8
step-by-step explanation:
5x - 4y = 40
x = 0
5(0) - 4y = 40
-4y = 40
/-4 /-4
y = -10
y = 0
5x - 4(0) = 40
5x = 40
/5 /5
x = 8
the line with go from the y-intercept -10 to the x-intercept 8
