Answer:

(-11, -6).

Step-by-step explanation:

8x-3y=-70

-2x+5y=-8     Multiply this equation by 4:

-8x+20y=-32

Now add this last equation to the first equation:

17y = -102   - we see that we have eliminated x.

y = -102/17

= -6.

Now plug y=-6 in the first equation to get x:

8x-3(-6)=-70

8x =-70 -18

8x =-88

x = -11.

Maria's age of 17 years less than Orlando's age. The sum of their ages is 33 find their ages.
weqwewe [10]
Maria´s age=x-17
Orlando´s age=x
We can suggest this equation:
(x-17)+x=33
2x=33+17
2x=50
x=50/2
x=25

Maria´s age=x-17=25-17=8
Orlando´s age=x=25.

Answer: Maria is 8 years old, and Orlando is 25 years old.
