Solution:
Solve the system of equations to find the value of y.
5x + 3y = 8
2(5x + 3y = 8)
10x + 6y = 16
Substitute the value of y into any equation to find the value of x.
- 10x + 10y = 40
- => 10x + 10(6) = 40
- => 10x + 60 = 40
- => 10x = -20
- => x = -2
Putting them in (x,y) form.
- (x,y) ⇒ (x = -2,y = 6) ⇒ (-2,6)
