Step-by-step explanation:
2x – y = 6
Answer:
-3 or -1 is a valid value for x
Step-by-step explanation:
We start by cross multiplying;
So the expression becomes;
x^2 + 5x + 6 = 1(x + 3)
x^2 + 5x + 6 = x + 3
x^2 + 5x -x + 6-3 = 0
x^2 + 4x + 3 = 0
x^2 + x + 3x + 3 = 0
x(x + 1) + 3(x + 1) = 0
(x + 3)(x + 1) = 0
x + 3 = 0 or x + 1 = 0
x = -3 or x = -1
The value of the expression is

Answer:Randy made 64 balloon animals and his sister made 32 balloon animals.
Step-by-step explanation:
Let x represent the number of balloon animals that Randi made.
Let y represent the number of balloon animals that her sister made.
Randi and her sister made balloon animals and sold the for. $0.50 each at the school carnival. They made $48.00. This means that
0.5x + 0.5y = 48 - - - - - - - - - -1
Randi made twice as many balloons as her sister. This means that
x = 2y
Substituting x = 2y into equation 1, it becomes
0.5 × 2y + 0.5y = 48
y + 0.5y = 48
1.5y = 48
y = 48/1.5 = 32
x = 2y = 2 × 32
x = 64
