Find the values of x and yy=-3x+55x=4y-3what is the answer to this question

Sagot :

Answer:

x = 1

y = 2

Explanations:

The system of equations is:

y = -3x + 5..........................(1)

5x = 4y - 3.......................(2)

Substitute equation (1) into equation (2)

The equation becomes:

5x = 4(-3x + 5) - 3

5x = -12x + 20 - 3

5x = 12x + 17

5x + 12x = 17

17x = 17

Divide both sides by 17

17x / 17 = 17 /17

x = 1

Substitute the value of x into equation (1)

y = -3x + 5

y = -3(1) + 5

y = -3 + 5

y = 2
