4x-5(3x+10)=126
7x-2(3+4x)=19
15+3(2x-9)=60
28-6(2x+4)=124
3(2x-1)+5=14
3(7x+9)=-15
15-(2x+7)=14

4x-5(3x+10)=126
4x - 15x - 50 = 126

Perito:
What am I going to do with you?
-5 * 10 = -50
4x-5(3x+10)=126
4x - 15x + 50 = 126 ; + should be -
Can you solve it now?
On the right hand side of ='s invokes a sign change
Count the x's: 4 -15
Count the #'s -50 -126
(4-15)x + (-50 - 126) = 0
