Carlos is half as old as Andre Andre is 15 years older than Carlos how old is Andre

Leokris [45]

Answer:

30 years old

Step-by-step explanation:

Let the two ages be A and C.

Then C = (1/2)A, and A = C + 15.

Substitute C + 15 for A in C = (1/2)A:

C = (1/2)(C + 15), or 2C = C + 15.

Then C = 15, and A = C + 15 becomes A = 15 + 15, or A = 30.

2x-y=3 -x-y=3 what does this equal system of equations

Jet001 [13]

Topic : Linear equations in two variables.

Given :

2x - y = 3 ––– (i)
- x - y = 3 ––– (ii)

Solution :

Now,

(i) – (ii)

$\qquad \sf \: { \dashrightarrow 2x - y - ( - x - y) = 3 - 3}$

$\qquad \sf \: { \dashrightarrow 2x - y + x + y) = 3 - 3}$

$\qquad \sf \: { \dashrightarrow 3x = 0}$

$\qquad \bf \: { \dashrightarrow x = 0}$

Now, substituting the value of x in Eq (i) :

$\qquad \sf \: { \dashrightarrow 2x - y = 3 }$

$\qquad \sf \: { \dashrightarrow 2(0)- y = 3 }$

$\qquad \sf \: { \dashrightarrow 0- y = 3 }$

$\qquad \bf \: { \dashrightarrow y = - 3 }$

Therefore,

The value of x = 0 and y = -3
