The answer should be D.
Step-by-step explanation:
You do the elimination process.
Answer:
D
Step-by-step explanation:
5x + 3y = 18 → (1)
2x - 3y = 10 → (2)
adding the 2 equations term by term will eliminate the y- term
7x + 0 = 28
7x = 28 ( divide both sides by 7 )
x = 4
substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
5(4) + 3y = 18
20 + 3y = 18 ( subtract 20 from both sides )
3y = - 2 ( divide both sides by 3 )
y = - [tex]\frac{2}{3}[/tex]
