Answer:
2(x-7) + 3 = 9
2x - 14 = 6
2x = 20
x = 10
Step-by-step explanation:
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
Simplify both sides:
x
—- = -9
4
now isolate the variable (x):
x= -9 • 4
x= -36
