Answer:

x=0

Step-by-step explanation:

8x + 4 = 3 ( x - 1 ) + 7

Distribute

8x +4 = 3x-3 +7

Combine like terms

8x+4 = 3x +4

Subtract 4 from each side

8x = 3x

Subtract 3x from each side

5x =0

x=0

Answer:

\boxed{x=0}

Step-by-step explanation:

8x+4=3(x-1)+7

Expand brackets.

8x+4=3x-3+7

8x+4=3x+4

Subtract both sides by 4.

8x=3x

Subtract 3x on both sides.

8x-3x=0

5x=0

Divide both sides by 5.

x=0

How do you solve 2/7m -1/7 = 3/14
Mars2501 [29]

the only thing you need to do is separate m:

2/7m= 3/14 + 1/7

2/7m= 5/14

m= (5/14)/(2/7)

m= 5/14 × 7/2

m= 35/28

m= 5/4
