Respuesta :
Answer:{d,t}={187, 17/2}
Step by step explanation :
System of Linear Equations entered :
[1] d - 18t = 34
[2] d - 22t = 0
Graphic Representation of the Equations :
-18t + d = 34 -22t + d
Solve by Substitution :
// Solve equation [2] for the variable d
[2] d = 22t
// Plug this in for variable d in equation [1]
[1] (22t) - 18t = 34
[1] 4t = 34
// Solve equation [1] for the variable t
[1] 4t = 34
[1] t = 17/2
// By now we know this much :
d = 22t
t = 17/2
// Use the t value to solve for d
d = 22(17/2) = 187

Answer:
[tex]d=52\\t=\frac{26}{11}[/tex]
Step-by-step explanation:
1 solve for d in d =18+34
solve for d
[tex]d=18+34[/tex]
Simplify 18+34 to 52
[tex]d=52[/tex]
2 substitute d=52 into d=22t
Start with the original equation
[tex]d=22t[/tex]
Let d=52
[tex]52=22t[/tex]
3 Solve for t in 52=22t
Solve for t
[tex]52=22t[/tex]
Divide both sides by 22
[tex]\frac{52}{22} =t[/tex]
Simplify [tex]\frac{52}{22}[/tex][tex]to \frac{26}{11}[/tex]
[tex]\frac{26}{11} =t[/tex]
Switch sides
[tex]t=\frac{26}{11}[/tex]
4 Therefore
[tex]d=52\\t=\frac{26}{11}[/tex]
