Question

-59 = -(b − -55) I keep getting these wrong on IXL... my brain hurts

Answer 1

-59 = -(b − -55)

Pretend that there is a -1 in front of the bracket.

-59= -1(b--55)

Multiply the bracket by -1

-59= -1(b)-1(--55)

-59= -b-55

Move -55 to the other side. Sign changes from -55 to 55

-59+55= -b-55+55

-59+55= -b

-4= -b

Multiply by -1

-4(-1)= -b(-1)

4= b

Answer: b= 4
