Question

2x + 5y = 19
y = 3x - 3
Solve for x and y

Answer 1

I dont know if i did this right but here

x1 = 9.5 y1 = 0

Answer 2

The values of x and y are 2 and 3 respectively .

Using the system of equation given:

• 2x + 5y = 19 __(1)
• y = 3x - 3 ___(2)

substitute (2) into (1)

2x + 5(3x - 3) = 19

2x + 15x - 15 = 19

17x = 34

x = 2

From (2)

y = 3(2) - 3

y = 6 - 3

y = 3

Hence, x and y are 2 and 3 respectively.
