X=y<br> x+2y =3<br> Solve using substitution

Zielflug [23.3K]

Answer:

Therefore the Final Solution is

x = 1 and y = 1

Step-by-step explanation:

Given:

$x=y$ ...............Equation ( 1 )

$x+2y=3$ ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Equating Equation ( 1 ) in Equation ( 2 ) we get

$y+2y=3\\\\3y=3\\\\y=\frac{3}{3} \\\\\therefore y =1$

Now Substituting y = 1 in Equation ( 1 ) we get

$x =1\\\\\therefore x=1$

Therefore the Final Solution is

x = 1 and y = 1

(-19+7i)-(29+32i)=<br><br> in the form (a+bi)

olga_2 [115]

ANSWER

$-48-25i$

EXPLANATION

We want to simplify the expression,

$(-19+7i) - (29+32i)$

Let us expand the bracket to obtain,

$-19+7i-29-32i$

We now group the complex number parts and real number parts.

$-19 -29+7i-32i$

We simplify further to obtain,

$- 48-25i$

This is in the form,

$a+bi$

where

$a=-48$

and

$b=-25$
