Question

What is the solution of 10 equals the absolute value of 7 minus 3 x.?

Answer 1

Ok so absolute value means you'll have two solution.
7-3x = 10
-3x = 3 ( move the 7 to the right hand side)
x = -1 ( divide both sides by -3)
and
7-3x = -10
-3x = -17 ( move 7 to the right hand side)
x = -17/-3 = 17/3 = 5.6666... ( divide both sides by -3)
so x = -1 and x = 5.6666 is a solution
