I help the my answer can help you
$370.00 - $40.00 = $330.00
$330.00 - $50.00 = $280.00
$280.00 + $210.00 = $490.00
Ellen now has $490.00 as her new balance.
Plug in 4 for x and solve equation like so. c=2
- Multiply (-2x-4) by -5:
[(-5)(-2x) + (-5)(-4)] +5x - 4 = -29
= 10x+20+5x-4=-29
- Combine Like Terms:
(10x+5x) + (20-4) = -29
15x+16=-29
- Subtract 16 from each side
15x+16 -16 = -29 -16
15x = -45
x = -3
