7/x = 84 / (156 -x)
84x = 7(156 -x)
84x = 1092 - 7x
91x = 1092
x = 12

AC = 156 - 12 = 144

A system of equations consists of a line s of the equation y = x - 5 that is graphed in orange, and a line t that passes through
Zarrin [17]

ANSWER

x =  4

and

y =   - 1

EXPLANATION

Line s has equation:

y=x-5

And line t has equation:

y =  -  \frac{3}{4}x  + 2

We equate the two equations to get:

x - 5 =  -  \frac{3}{4} x + 2

Multiply through by 4

4x - 20  =  -  \frac{3}{4} x \times 4 + 2 \times 4

4x - 20  =  - 3 x  + 8

4x + 3x   =  8 + 20

7x=28

x =  \frac{28}{7}  = 4

y =  4  - 5 =  - 1
