Question

solve 7x+7= 56 and check
your answer​

Answer 1

Answer:

x = 7

Step-by-step explanation:

7x + 7 = 56

7x = 56 - 7

7x = 49

x = 49 / 7

x = 7

Checking or verifying the answer

substitute 7 in place of x

7 × 7 + 7  ⇒ 49 + 7  = 56

Answer 2

Answer:

=> x = 7

Step-by-step explanation:

Given that:-

$7x+7= 56$

As we have to find the value of the equation,

For simplifying this expression we have to use the transposition method:

We have,

=> $7x+7= 56$

Subtract $7$ on both sides,

=> $7x+7-7= 56-7$

Simplifying it further, we get

=> $7x = 49$

Divide both the sides by $7$,

=> $x = 7$

Hence, the required solution is 7.

Now, plug the value of x in the equation,

=> $7x+7= 56$

=> $7(7)+7= 56$

=> $49+7=56$

=> 56 = 56

LHS = RHS
