Y=-2x+4 y=6x+12 substitution method
1 answer:
Answer:
x = - 1, y = 6
Step-by-step explanation:
Given the 2 equations
y = - 2x + 4 → (1)
y = 6x + 12 → (2)
Substitute y = 6x + 12 into (1)
6x + 12 = - 2x + 4 ( add 2x to both sides )
8x + 12 = 4 ( subtract 12 from both sides )
8x = - 8 ( divide both sides by 8 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 6(- 1) + 12 = - 6 + 12 = 6
Solution is (- 1, 6 )

Answer:
Step-by-step explanation:
a(1) = -7 (given)
a(2) = a(1) + 4 = -7 + 4 = -3
a(3) = a(2) + 4 = -3 + 4 = 1
a(4) = a(3) + 4 = 1 + 4 = 5
and so on.
