Respuesta :
y = 5x + 2 . . . . . . . . . . (1)
3x = -y + 10 . . . . . . . . (2)
3x = -(5x + 2) + 10
3x = -5x - 2 + 10
3x + 5x = -2 + 10
8x = 8
x = 1
y = 5(1) + 2 = 5 + 2 = 7
Solution is (1, 7)
3x = -y + 10 . . . . . . . . (2)
3x = -(5x + 2) + 10
3x = -5x - 2 + 10
3x + 5x = -2 + 10
8x = 8
x = 1
y = 5(1) + 2 = 5 + 2 = 7
Solution is (1, 7)
The solution to the system of equations y = 5x + 23 and x = -y + 10 is (1,7)
How to determine the solution?
The equations are given as:
y = 5x + 2
3x = -y + 10
Substitute y = 5x + 2 in the second equation
3x = -5x - 2 + 10
Collect like terms
3x + 5x = -2 + 10
This gives
8x = 8
Divide
x = 1
Substitute x = 1 in y = 5x + 2
y = 5 * 1 + 2
y = 7
Hence, the solution to the system of equations is (1,7)
