Answer:
52/3
Step-by-step explanation:
Use basic Thales therom,

Cross multiply,
3*(5x-8)=4*(3x+7)
3*5x - 3*8 = 4*3x + 4*7
15x - 24 = 12x +28
Add 24 to both sides
15x = 12x + 28 + 24
15x = 12x + 52
Subtract 12x from both sides
15x-12x =52
3x = 52
Divide both sides by 3
x = 52/3
Answer:
(-5,17) is a solution to the equation
Step-by-step explanation:
The equation is y = -2x+7
Substitute the values of x=-5 and y =17 into the equation and see if it is true
17 = -2(-5) +7
17 = 10+7
17=17
This is true so (-5,17) is a solution to the equation
