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

Can you solve it now?

What am I going to do with you?

-5 * 10 = -50

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

Perito is getting tired :rolleyes: That's the second one I see in the same week...
