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!!!

step-by-step explanation:

5389/6 = 898.1666667

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
