Answer:
B) addition property
Step-by-step explanation:
thinking that 3x - 30 - 0 should equal 0.
3x - 30 - 0 = 0
to get rid of numbers on side with variables, we have to add them to both sides (to make it 0 in side with variable.)
3x - 30 - 0 = 0
+30 +0 = +30 +0
3x = 30 <- step 4
Answer:Infinitely many
Step-by-step explanation: so first u Simplify 3x + 6 = -1 - 3 + 4x to get 3x+6=4x−4
than u Subtract 3x from both sides to get 6=x−4.You add 6+4 to get 10 . which than u will have 10=x than u Switch sides to get x =10
