Question

Solve the equation. 3(x – 9) = 30

x = 1
x = 13
x = 19
x = 57

Answer 1

Hello and Welcome to OpenStudy! :)
for 3(x - 9) = 30 first distribute
so 3*x - 3*9 = 30
3x - 27 = 30 then add 27 to both sides
+27 +27
3x = 57 then divide both sides by 3
so x = 57/3 = ?

Answer 2

@jigglypuff314 does that mean divided 53 by 3 ? if it does then that equals 17.6?

Answer 3

57 divided by 3 :)

Answer 4

becaues when you add 27 to both sides
30 + 27 = 57
