What is the x and the y

Ghella [55]

Answer:

$x=5\\\\y=-8$

Step-by-step explanation:

Given Equation:

$-7x-10y=45\\\\$ Equation:1

$-3x-5y=25$ Equation:2

Multiplying Equation:2 by '2':

$-6x-10y=50$ Equation:3

Using Elimination Method: Subtracting Equation:1 from Equation:3:

$-6x-10y-(-7x-10y)=50-45$

$-6x-10y+7x+10y=5\\\\$

Solving Like terms:

$-6x+7x=5\\\\x=5$

Put the value of 'x' in Equation:2

$-3x-5y=25$

$-3(5)-5y=25\\\\-15-5y=25$

Adding '15' both sides:

$-5y=25+15\\\\-5y=40$

Dividing by '-5' both sides:

$y=40/-5\\\\y=-8$

The values of 'x' and 'y' are:

$x=5\\\\y=-8$
