Question

x+y=11; 2x-3y=7. in elimination method 9th grade​

Answer 1

Answer:

Shearing, also known as die cutting, is a process which cuts stock without the formation of chips or the use of burning or melting. Strictly speaking, if the cutting blades are straight the process is called shearing; if the cutting blades are curved then they are shearing-type operations.

Answer 2

Step-by-step explanation:

1. we can write the equation (1) x+ y =11
2. (2) 2x-3y=7

• multiple by 2 Of equation (1)
• multiple by 1 of equation (2)
• we can get the 2x+ 2y = 22

2x-3y= 7

- + -

we can change sing for cancel turm 5y = 15

y= 15/5

y= 3

we can put this value equation (1)

x+y = 11

x + 3 = 11

x= 11-3

x= 8

we can get the value (x, y)

(8 ,3)
