7 x 5e = 105

plz help ​

Simplifying

7(x + 5) = 105

Reorder the terms:

7(5 + x) = 105

(5 * 7 + x * 7) = 105

(35 + 7x) = 105

Solving

35 + 7x = 105

Solving for variable 'x'.

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

Add '-35' to each side of the equation.

35 + -35 + 7x = 105 + -35

Combine like terms: 35 + -35 = 0

0 + 7x = 105 + -35

7x = 105 + -35

Combine like terms: 105 + -35 = 70

7x = 70

Divide each side by '7'.

x = 10

Simplifying

x = 10
