Question

Which equation is true when x= -9?​

Answer 1

Answer:

2(4-x)=26

Step-by-step explanation:

1. Plug "-9" into each equation as "x"

2(4--9)=26

5(-9)+30=75

5(12--9)=15

3(-9+11)=-16

2. Solve each equation

2(4--9)=26 ~ 26=26

5(-9)+30=75 ~ -5=75

5(12--9)=15 ~ 105=15

3(-9+11)=-16 ~ 6=-16
