Question

2x-3y=-3;5x – 4y =10​

Answer 1

Объяснение:

1) 2x-3y=-3

2x-3y+3=0

Ответ: 0

2) 5x-4y=10

5x-4y-10=0

Ответ:0

Answer 2

$\blue{2x-3y=-3}$

$\red{2x-3 \times 0=-3;}$

$\blue{5x - 0 = - 3}$

$\fbox{5x = - 3}$

$\blue{5x - 4y =10}$

$\purple{5x - 4 \times 0 = 10}$

$\pink{5x - 0 = 10}$

$\red{5x = 10}$

$\fbox{x = 2}$

Answer 3

To solve the system of equations:

2x - 3y = -3 ---(1) 5x - 4y = 10 ---(2)

There are multiple ways to solve this system, but I'll use the method of substitution.

Step 1: Solve equation (1) for x in terms of y. 2x - 3y = -3 2x = 3y - 3 x = (3y - 3)/2

Step 2: Substitute the value of x in equation (2). 5x - 4y = 10 5((3y - 3)/2) - 4y = 10 (15y - 15)/2 - 4y = 10 15y - 15 - 8y = 20 15y - 8y = 20 + 15 7y = 35 y = 35/7 y = 5

Step 3: Substitute the value of y back into equation (1) to find x. 2x - 3(5) = -3 2x - 15 = -3 2x = -3 + 15 2x = 12 x = 12/2 x = 6

Therefore, the solution to the system of equations is x = 6 and y = 5.
