Answer:

Multiply the second equation by -2

Step-by-step explanation:

Multiplying equation (II) by -2 makes it easy to continue the equation by elimination method.

the second equation becomes 3c -4d = 32.

Such that it becomes:

5c + 4d = 10... (I)

-6c -4d = -32... (III)

adding equation (1) and (III)

-c = -22

c = 22.

Hope its clear!?

Solve the following equation <br><br>6x-1=3 (2x+4)-1

DIA [1.3K]

$6x - 1 = 3(2x + 4) - 1$
Distribute
$6x - 1 = 6x + 12 - 1$
Combine like terms
$6x - 1 = 6x + 11$
Add 1 and subtract 6x from each side
0 = 12
The equation has no real solution
