I'm going to assume that the equation is 6 + (-5 - 7)
~Solve what's in parenthesis
6 + (-12)
~Simplify
6 - 12
~Subtract
-6

Let X = number of Giraffes
Number of elephants = 3X - 4
Because it was stated that there are more than 23 elephants, the number should not fall below 23.
The algebraic expression would be:
3X - 4 = 23
To get X; Transfer -4 to the other side, changing its sign to positive.
3X = 23 + 4
3X = 27
To get X; Divide both sides by 3
X = 27 / 3
X = 9
Since X represents the number of giraffes, then, there are 9 giraffes in the zoo.
To Check: Substitute X with 9 in the algebraic expression.
3X - 4 = 23
3(9) - 4 = 23
27 - 4 = 23
23 = 23 EQUAL
Answer:
12 units²
Step-by-step explanation:
A(triangle) = 1/2(2)(2) = 2 units²
A(triangle) = 1/2(2)(6) = 6 units²
A(Square) = 2(2) = 4 units²
A(Shape) = 2 + 6 + 4 = 12 units²
Plug 1 in for x to get 7y=3(1)-7
7y=-4
y=-4/7
