Answer:
x = 0.9
Step-by-step explanation:
It is convenient to clear fractions by multiplying the equation by the product of the denominators. That gives ...
0.5(4x +9) = 3x(7/3)
Multiplying by 2 will give you ...
4x + 9 = 14x
Subtract 4x
9 = 10x
And divide by 10
9/10 = x
Answer:

Answer:
Step-by-step explanation:
if you have negative numbers of x (this means negative meters) then the equation transform them into negative yards.
then replace y by 40yd in the equation like
40 = 1.09x
x = 40/1.09 = 36.7 meters
so in a 40yd race, there are 36.7 meters.
