Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5x+4x−68=34−8x

5x+4x+ −68=34+ −8x

(5x+4x)+(−68)=−8x+34(Combine like terms)

9x+−68=−8x+34

9x−68=−8x+34

Step 2: Add 8x to both sides.

9x −68+ 8x= −8x +34 +8x

17x −68 =34

Step 3: Add 68 to both sides.

17x −68 +68= 34 +68

17x=102

Step 4: Divide both sides by 17.

17x /17=  102/17

                                X=6   > final answer hope i could help :)

Step-by-step explanation:

Let's step through this line by line, looking for a spot where the friend could have made a mistake.

5x+4x-68=34-8x\\5x+4x=102-8x\\5x+4x+8x=102\\17x=102\\x=6

So, where could the friend have made their mistake? The key here is the transition from step 1 to step 2. What if we had subtracted 68 instead of adding it?

5x+4x-68=34-8x\\5x+4x=-34-8x\\5x+4x+8x=-34\\17x=-34\\x=-2

There it is. The friend's problem was that they had accidentally <em>subtracted</em> 68 to both sides when they should have <em>added</em> it.

5,7,9,11 12th term pls help
skad [1K]

Answer:

27

Step-by-step explanation:

5,7,9,11. ....

This is an arithmetic sequence.

First term = a₁ = 5

Common difference = d = second term - first term = 7 - 5 = 2

nth term = a₁ + (n-1)*d

12th term = 5 + (12 - 1) * 2

                = 5 + 11*2

                = 5 + 22

                = 27
