Answer:
x = 4
Step-by-step explanation:
7x - 4 = 5x + 4
7x-4-5x = 5x+4-5x
2x-4 = 4
2x-4+4 = 4 + 4
2x = 8
2x / 2 = 8/ 2
All the sides of a rhombus are equal and opposite sides parallel and equal.
Therefore by understanding the above we can deduce that:
7x - 4 + 4 - 5x = 5x + 4 + 4 - 5x (Separate all the terms with x to go to the other side of the equals sign and do the some for the constants).
7x - 5x + (4 - 4) = (5x - 5x) + 4 + 4
7x - 5x = 4 + 4
2x/2 = 8/2
5
ALL SIDES MUST BE THE SAME
3,-19
-5
The answer is -5 because we have -2 as x. The function is h(x)=3x+1. 3 times -2=-6. When we add 1 to the result, we have -5 as the answer. Hope it helps!
