Question

7x +7=56 solve the equation and check the answer​

Answer 1

Answer:

x=7

Step-by-step explanation:

Subtract 7 from both sides of the equation

7x+7=56

7x+7-7=56-7

Simplify

subtract the number

7x+7-7=56-7

7x=56-7=49

Divide both sides of the equation by the same term

7x/7

49/7

Cancel terms that are in both the numerator and denominator

x=49/7=7

Answer 2

$\: \: \: →7x + 7 = 56 \\ \\ \: \: \: \: \: → 7x = 56 - 7 \\ \: \\→ 7x = 49 \\ \\→ x = \frac{49}{7} \\ \\ \boxed{\sf\purple{x = 7}}$

${\boxed{\sf{Verification:}}}$

$7x + 7 = 56$

$\: \: \: \: LHS = 7x + 7 \\ \\ \: \: \: \: \: \: RHS = 56 \: \: ┈┈┈ \:( 1)$

$For \: \: x = 7 \:$

$\: \: \: \: \: = 7 \times 7 + 7 \\ \\ = 49 + 7 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: = 56 \: \: ┈┈┈(2)$

$From \: (1) \: and \: (2)$

$\: LHS = RHS \:$
