Linear equation: -1
Anika [276]

Answer:

The right answer is:

the addition property of equality and then the division property of equality

Step-by-step explanation:

Given equation and steps to solve it are:

Step 1: –3x – 5 = 13

Step 2: –3x = 18

Step 3: x = –6

In step two, -5 has to be removed from left hand side of the equation so additional property of equality will be used i.e. adding 5 on both sides

Similarly in the third step, to remove -3 with x , division property of equality will be used i.e. dividing both sides by -3

Hence,

The right answer is:

the addition property of equality and then the division property of equality

Solve the system of equations x – 2y = -19 and - 3x + 5y = 48 by combining<br> the equations.
mr_godi [17]

Answer:

x= -1

y = 9

Step-by-step explanation:

to solve this system of equation

let

x - 2y = -19.....................................equation 1

-3x + 5y = 48 .................................. equation2

from equation 1

x - 2y = -19.....................................equation 1

x = -19 + 2y................................... equation 3

substitute the value of x into equation 2

-3x + 5y = 48 .................................. equation2

-3(-19 + 2y) + 5y = 48

57 - 6y + 5y = 48

combine the like terms

-6y + 5y = 48 -57

-y = - 9

divide both side by -

y = 9

put y= 9 into equation 3

x = -19 + 2y................................... equation 3

x = -19 + 2(9)

x = -19 + 18

x = -1

therefore the value of x and y is -1 and 9 respectively
