Answer:
(-3u^2 + 7u - 2) + (4u^2 + 6u + 1)
= -3u^2 + 7u - 2 + 4u^2 + 6u + 1
= 4u^2 - 3u^2 + 7u + 6u + 1 - 2
= u^2 + 13u - 1

So this can be solve by establish two equation:
let x be age of montell
y be tha age of her mom
for the first equation (<span>Montell is 30 years)</span>:
x = y - 30
second equation ( in 5 years )
x + 5 = ( y + 5 ) ( 1/3)
solving the equation simultaneously
x = 10 years old
y = 40 years old
X=2
you multiply by 8 on both sides. so that your equation now looks like x-2=0
then you will add by 2 on both sides.
x=2
