Answer:
0= 30
Step-by-step explanation:
-7(3x+5) +20=5)3-5x)+4x
-21x-35+20=5)3-5x)+4x
Add the numbers
-21x-35+20=5)3-5x)+4x
-21x-15=5)3-5x)+4x
Rearrange terms
-21x-15=5)3-5x)+4x
-21x-15=5(-5x+3)+4x
Distribute
-21x-15=-25x+15+4x
Combine like terms
-21x-15=-21x+15
Add 15 to both sides of the equation
-21x-15+15=-21x+15+15
Simplify
Add the numbers
-21x=-21x+30
add 21 to both sides of the equation
-21x+21x= 21x+30+21x
Simplify
combine like terms
0=30
