Answer:
a) x = 7.5
b) x = 1
Step-by-step explanation:
a)
- (4x - 1)/2 = x + 7
- 4x - 1 = 2(x + 7)
- 4x - 1 = 2x + 14
- 2x = 15
- x = 15/2 or 7.5
b)
- 3x + 2 = (2x +13)/3
- 3(3x + 2) = 2x + 13
- 9x + 6 = 2x +13
- 7x = 7
- x = 1
Pythagoras' theorem
a squared + b squared = c squared
c is the hypotenuse
