14= 2x + 5x + 7

14= 7x + 7 (Add similar terms)

14 – 7 = 7x + 7 – 7 (Subract 7 from both sides.)

7 = 7x

7x/7 = 7/7 (Divide by 7 on both sides)

x = 1

Hope that makes it easy

And if you want to confirm then put 1 in place of x and see if it is right.

14 = 2(1) + 5(1) + 7

14 = 2 + 5 + 7

14 = 14

See it works.

2x + 5x + 7 =14

1. Add like terms, so 2x + 5x = 7x

2. Subtract 7 from both sides, so 7x +7 -7 = 14 – 7

2. You will get: 7x = 7

3. Divide 7 to both sides, so 7x/7 = 7/7

4. The answer is: x = 1

well if u just check 2 + 5 +7 = 14 so x=1

2 x 1 + 5 x 1 + 7 = 14

First, combine the 2x and 5x to get 7x. Then, subtract the 7 from both sides so that the Xs are by themselves. Then, divide both sides by to get the X completely isolated.

2x+5x=7x

7x+7=14

7x=14-7

7x=7

x=1

combine like terms

14=2x + 5x + 7

14= 7x + 7

14-7 = 7x

7= 7x

x=1

and you can plug your answer which is 1 into x to check that the statement is true.

2(1) + 5(1) + 7 = 14

2 + 5 + 7 = 14

14=14

so therefore your answer is right.

14 = 2x + 5x +7

14 = 7x + 7

Subtract 7 from each side to equal =

7 + 7x

Divide each side by seven to equal =

x = 1.

-7 -7

7 = 2x + 5x

7 = 7x

/7 = /7

1 = x

you always begin by combining similar terms. In this case it would be the x’s. so you combine 2x and 5x. That leaves you with

14=7x + 7

then you subtract 7 on both sides and you get 7x=7. And then divide by 7 on both sides to isolate the x term. That leaves you with x = 1

14=2x + 5x +7

add like terms

14=7x+7

subtract 7 from each side

7=7x

divide each side by 7

1=x

x=1
