Answer:
x=25
Step-by-step explanation:
Assuming you meant 3x = 75 what you want to do is isolate x. To isolate x you want to work backward. Since it is 3 times x you want to divide each side by 3 to get x on its own.
(3x)/3 = (75)/3
When you divide 3 and 3 you get one. 1x is represented by just an x so x=25.
False. Not all triangles are equilateral.
