<h3>Question:</h3>

Which operation should be used to solve x + 7 = 19?

÷ 7

– 7

x 7

+ 7

<h2>Answer:</h2>

-7 is the correct answer.

<h3>Solution:</h3>

Because when we'll use -7 then the 7 in the LHS will get cancelled.

x + 7 = 19

or, x + 7 - 7 = 19 - 7

or, x = 12

Answer:

5 + 2x=2x + 6

Subtract 5 from both sides.

2x =2x + 6 - 5

Combine like terms (numbers).

2x = 2x + 1

Subtract 2x from both sides.

0 = 1

Since 0 doesn’t equal 1, there is no real solution to the problem.

Oksanka [162]

Answer:

Part A: 1148

Part B: 545

Step-by-step explanation:

Part A: 2x + 58

Part B: x

2x + 58 + x = 1693

3x + 58 = 1693

3x = 1635

x = 545

Part A: 2x + 58 = 2(545) + 58 = 1148

Part B: x = 545
