Can someone pls solve these questions i will mark them as brainiest

1) Simplifying

6m + 5 = 20

Reorder the terms:

5 + 6m = 20

Solving

5 + 6m = 20

Solving for variable 'm'.

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

Add '-5' to each side of the equation.

5 + -5 + 6m = 20 + -5

Combine like terms: 5 + -5 = 0

0 + 6m = 20 + -5

6m = 20 + -5

Combine like terms: 20 + -5 = 15

6m = 15

Divide each side by '6'.

m = 2.5

Simplifying

m = 2.5

2) There is a theorem which says exterior angle of a triangle is equal to sum of opposite interior angles.

So, let the other interior angle be x

According to the theorem

x+70 = 120°

x=50°

3) i will solve and tell you in the comments

4) Let the number be x

5x - 68 = x

5x - x = 68

4x = 68

x = 68/4 = 17

5) i will solve this too

(mark me brainliest please I need 2 more)

THANK YOU
