Answer: The answer to a system of equations is the point(s) of intersection of the equation involved.
When you have more than one equation with more than one variable, you have a system of equation. The solution(s) is the set of values for each variable that satisfy the equations. This means that the inputting values make the equations true.
Answer:
-34
Step-by-step explanation:
Remove all brackets by multiplying the existing math signs then take it from there
34= ( r + 4) * t
18 = ( r - 4) * t
solve for time in both equations
34/ (r + 4) = t
18 / (r - 4) = t
time is the same . so we can set them equal
34/ (r + 4) = 18 / (r - 4)
the answer is r = 13
