X - 3y = 4<br> 2x - 5y = 8 <br> solve by substitution

Shkiper50 [21]

Answer:

y = 0

x = 4

Explanation:

x - 3y = 4

2x - 5y = 8

<u>make x the subject,</u>

x - 3y = 4

x = 4 + 3y __ equation 1

2x - 5y = 8

x = (8+5y)/2 __ equation 2

<u>using substitution method:</u>

(8+5y)/2 = 4 + 3y

8 + 5y = 8 + 6y

6y - 5y = 8 - 8

y = 0

Find x,

x = 4 + 3y

x = 4 + 3(0)

x = 4
