Solve using the addition and multiplication principles. 7+3x<19
The solution set is {x|x blank blank}
7+3x < 19
we just solve it like a normal equation (not an equality).
7 + 3x < 19
3x < 19 - 7
3x < 12
x < 4
hope this helps~ :)
To solve the inequality 7 + 3x < 19 using the addition and multiplication principles, we need to isolate the variable x.
First, let's subtract 7 from both sides of the inequality:
7 + 3x - 7 < 19 - 7
3x < 12
Now, to isolate x, we divide both sides of the inequality by 3:
(3x) / 3 < 12 / 3
x < 4
So, the solution set is {x | x < 4}.
