Solve for x: <br><br> 5x + 6 = 8x + 12

ICE Princess25 [194]

Answer:

x=-2

Step-by-step explanation:

Step 1: Subtract 8x from both sides.

5x+6−8x=8x+12−8x

−3x+6=12

Step 2: Subtract 6 from both sides.

−3x+6−6=12−6

−3x=6

Step 3: Divide both sides by -3.

−3x

−3

=

6

Find the solution of the system of equations. – 5 - 6y = -32 4x - 6y = 4

amid [387]

Equation (1)

$-5 - 6y = -32$

Equation (2)

$4x - 6y = 4$

Get y alone in equation (1)

$-5 - 6y = - 32\\-6y = -32 + 5\\-6y = -27\\y = \frac{-27}{-6} = \frac{9}{2}$

Insert y in equation (2)

$4x - 6 \cdot \frac{9}{2} = 4\\4x - 27 = 4\\4x = 4 + 27\\4x = 31\\x = \frac{31}{4}$
