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]
