Answer:
Step-by-step explanation:
x = 2
step-by-step explanation:
if sr parallel to ba then the sides bc and ac are in proportion, that is
\frac{sb}{cs} = \frac{ra}{cr} ← substitute values
\frac{4x+1}{2x} = \frac{13.5}{6} ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
x = 2

Answer:
- 2x - Зу = - 9
9x +9y = 0
<=>
-6x - 9y = -27
9x +9y = 0
<=>
3x =-27
=> x = -9
=> y = -x = 9
