Answer 1

Answer:

Simplifying

Simplifying

21 + x = 70

Solving

21 + x = 70

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-21' to each side of the equation.

21 + -21 + x = 70 + -21

Combine like terms: 21 + -21 = 0

0 + x = 70 + -21

x = 70 + -21

Combine like terms: 70 + -21 = 49

x = 49

Simplifying

x = 49

Answer 2

$\huge\text{Hey there!}$

$\large\textsf{21 + x = 70}$

$\large\textsf{x + 21 = 70}$

$\large\text{SUBTRACT 21 to BOTH SIDES}$

$\large\textsf{x + 21 - 21 = 70 - 21}$

$\large\text{CANCEL out: 21 - 21 because that gives you 0}$

$\large\text{KEEP: 70 - 21 because that helps solve for the x-value}$

$\large\textsf{x = 70 - 21}$

$\large\textsf{\bf x = 49}$

$\boxed{\boxed{\huge\text{Therefore, your answer is: \textsf{x = 49}}}}\huge\checkmark$
