Hi there!
From my best knowledge I assume this has to do with triangle angles and linear expressions.
All triangles add up to 180°, so we will use this formula with the triangle angels given.
(4m + 6) + (5m + 3) = 180°
9m + 9 = 180°
(Combined like terms) 4+5 & 6+3
9m = 171 (Subtract 9 from 180 = 171)
m = 19 (Divide 9 from 171)
So, m in the expression equals 19 but let’s double check.
(4(19) + 6) + (5(19) + 3) = 180
4 x 19 = 76 + 6 = 82°
(So that angle separately is 82 degrees.)
5 x 19 = 95 + 3 = 98°
(So that angle separately is 98 degrees.)
Add both angles - 82° + 98° = 180°
So it’s a true formula! Both angles in the triangle add to 180 as it should.
But as for the original question being asked, yes m = 19
= m = 19
