I am guessing this is an expression that needs to be simplify or factorise or both.
If the expression goes like this and I repeat :
2 1/2 x - 3/4 (2x+5) + 3/8
5x/2 - 3x/2 - 15/4 + 3/8
5x/2 - 6x/2 - 27/8
-x/2 - 27/8
-(4x + 27)/8 Answer:
Please comment me back if I got the question incorrect.
Hi there!

We can begin by setting the two expressions equal to solve for t:
2t - 1 = 5t
Subtract 2t from both sides:
-1 = 3t
Divide both sides by 3:
t = -1/3
Plug in this value of t into x(t) and y(t):
x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3
y(-1/3) = 5(-1/3) = -5/3
Thus:
(-5/3, -5/3) are the corresponding coordinates.
A ratios says how much of one thing there is compared to another thing and the trick with ratios is to always multiply or divide the numbers by the same value
