Set up your equation:
1 = 7x - 3
Add 3 to both sides:
7x = 4
Divide both sides by 7:
x = 4/7
Hope this helps!
4 2/3 = 14/3
15 = 15/1
14/3 * 15/1 = 14*15=210, 3*1 = 3
210/3 = 70
answer is 70
Answer:
x = 14
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, hence
4x + 14 + 2x + 15 + 5x - 3 = 180
11x + 26 = 180 ( subtract 26 from both sides )
11x = 154 ( divide both sides by 11 )
x = 14
