x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9
x = 9
The triangle has all 3 sides congruent and is thus an equilateral triangle.
Each angle = 60°
equate 7x - 3 = 60 and solve for x ( add 3 to both sides )
7x = 63 (divide both sides by 7 )
x = 
= 9
