What should you substitute for y in the second equation (bottom equation) in order to solve the system by the substitution method? (5x+ y = 10 3x - 2y = 6. O A. 0.2y + 2 B. -5x + 10 + O C. 1.5x+3 O D. 5x - 10

Answer :

5x + y = 10

3x - 2y = 6

ok

The question mentions that we need to leave alone y in the first equation.

5x + y = 10 Just pass 5x to the other side of the equation

if it has a positive sign, we change the sign to a negative

one.

that's all

y = -5x + 10 This is the answer

Letter B is the correct answer
