Answer:
w = - z
Step-by-step explanation:
Given
5w + 9z = 2z + 3w ( subtract 3w from both sides )
2w + 9z = 2z ( subtract 9z from both sides )
2w = - 7z ( divide both sides by 2 )
w = - z
Answer:
A
Step-by-step explanation:
To determine which point is a solution, substitute the x- coordinate into the equation and if the value obtained agrees with the y- coordinate of the point then it is a solution.
A (- 3, - 17)
y = 4(- 3) - 5 = - 12 - 5 = - 17 ← (- 3, - 17) is a solution
B (4, 7)
y = 4(4) - 5 = 16 - 5 = 11 ≠ 7 ← not a solution
C (- 2, - 18)
y = 4(- 2) - 5 = - 8 - 5 = - 13 ≠ - 18 ← not a solution
D (3, 17)
y = 4(3) - 5 = 12 - 5 = 7 ≠ 17 ← not a solution
