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

{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

Step-by-step explanation:

1 solve for d in d =18+34

solve for d

Simplify 18+34  to  52

2 substitute d=52 into d=22t

Start with the original equation

Let d=52

3 Solve for t in 52=22t

Solve for t

Divide both sides by 22

Simplify  

Switch sides

4 Therefore
