Can some one pls Use elimination to solve each system of equations

2x - y = -1
3x - 2y = 1

Correct  x = - 3  and y = - 5

Step-by-step explanation:

Given:

2 x - y = - 1

3 x - 2 y = 1

We will multiply first equation with number (- 2) and get:

- 4 x + 2 y = 2

then we add this equation to another and get:

- 4 x + 3 x = 2 + 1

- x = 3 / · (- 1)

x = - 3

now we replace x = - 3  in the first equation and get:

2 (- 3) - y = - 1  ⇒ - 6 - y = - 1 / ·(- 1)  ⇒ 6 + y = 1  y = 1 - 6 = - 5

y =- 5

God is with you!!!

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
