Answer:
(3, - 2 )
Step-by-step explanation:
Given the 2 equations
4x - 2y = 16 → (1)
y = - 5x + 13 → (2)
Substitute y = - 5x + 13 into (1)
4x - 2(- 5x + 13) = 16 ← distribute and simplify left side
4x + 10x - 26 = 16
14x - 26 = 16 ( add 26 to both sides )
14x = 42 ( divide both sides by 14 )
x = 3
Substitute x = 3 into (2) for corresponding value of y
y = - 5(3) + 13 = - 15 + 13 = - 2
solution is (3, - 2 )
2(11+13) = 26+2w because 2(11)=22 2(13)=26
