Isolate for x
First expand the bracket to
12x^2 - 15x = 12x - 5
Move everything to one side
12x^2 - 27x + 5
Use quadratic formula and sub in values
X = 2.046989
X = 0.203610
Step-by-step explanation:
So, we will take one of the numbers = x
And the other is 12 more than 3 times it, so = 3x + 12
So they said if we add them, we will get 4
So x + (3x + 12) = 4
4x + 12 = 4
4x = 4 - 12
4x = - 8
x = - 8 ÷4
x = - 2
So one of the numbers x = - 2
The other is 3x + 12
So x = - 2
3x +12 = 3(-2) + 12
= 6
So the 2 numbers = 6 and - 2
Lets check!
6 + (-2) = 4
So it's right!
The property of division.
Both sides are divided by 5.
“The division property of equality states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal.”

b g b
b g g two out of four have oldest two boys 2/4 = 1/2
Answer:
True
Step-by-step explanation:
g(f(0)= -5(2(0)-3)
g(f(0)= -5(0-3)
g(f(0)=-5(-3)
g(f(0)= 15
