Question

y = 5x and 2x + 3y = 34

(- 5x + y = 0)(-3)→ 15x - 3y = 0
2x + 3y = 34 → 2x + 3y = 34

2x + 3(5x) = 34
5x = 2x + 3y
5x + (2x + 3y) = 34
5x - (2x - 3y) = -34

its the second one right?

Answer 1

I'm trying to get this part
2x + 3(5x) = 34
5x = 2x + 3y
5x + (2x + 3y) = 34
5x - (2x - 3y) = -34


What have you tried to do?

Answer 2

oops sorry i missed a part of the proiblem my bad


Choose the correct first step(s) to solve the system using substitution.
y = 5x and 2x + 3y = 34

A) (- 5x + y = 0)(-3)→ 15x - 3y = 0
2x + 3y = 34 → 2x + 3y = 34

B) 2x + 3(5x) = 34
C) 5x = 2x + 3y
D) 5x + (2x + 3y) = 34
E) 5x - (2x - 3y) = -34
