Question

D=18+34 d=22t system of equations

Answer 1

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 2

Answer:

$d=52\\t=\frac{26}{11}$

Step-by-step explanation:

1 solve for d in d =18+34

solve for d

$d=18+34$

Simplify 18+34  to  52

$d=52$

2 substitute d=52 into d=22t

Start with the original equation

$d=22t$

Let d=52

$52=22t$

3 Solve for t in 52=22t

Solve for t

$52=22t$

Divide both sides by 22

$\frac{52}{22} =t$

Simplify  $\frac{52}{22}$$to \frac{26}{11}$

$\frac{26}{11} =t$

Switch sides

$t=\frac{26}{11}$

​4 Therefore

$d=52\\t=\frac{26}{11}$
