Answer:
(-3, 2)
Step-by-step explanation:
x + y = -1 = x = -1 - y
-3( -1 -y ) -4y = 2
4 + 3y - 4y = 2
-y + 4 = 2
-y = -2
y = 2
x + 2 = -1
x = -3
A) Kara's fee for the second child is $5
Use distributive property.
4(m - 2) = 24
Add 8 on both sides to leave the variable on one side.
4m - 8 = 24
+8 +8
Divide 4 on both sides.
4m = 32
---- ------
4 4
You'll get a solution of 8.
m = 8
Check:
4(8 - 2) = 24
32 - 8 = 24
24 = 24
