Question

Solve for x: -3|x + 7| = -12

x = 5 over 3, x = −19 over 3

x = −3, x = −11

x = −3, x = 11

No solution

Answer 1

first divide the "-3" over

|x+7| = 4

split into 2 cases

x+7 = 4

x+7 = -4

then solve for "x" for each equation

Answer 2

-3|x + 7| = -12

Divide by -3

|x + 7| = 4

x+7=4 or x+7=-4
x=4-7 or x=-4-7
x=-3 or x=-11

Answer 3

ok
