Answer:
x = , y =
<u>Explanation</u>:
2x - y= 2
3y= 4x - 5
<u>Make y the subject:</u>
2x - y= 2
-y = 2 - 2x
y = 2x - 2 <em>.........equation 1 </em>
3y= 4x - 5
y = (4x - 5)/3<em> ........equation 2</em>
From equation 1 and 2 solve them simultaneously:
→ (4x - 5)/3 = 2x - 2
→ 4x - 5= 3(2x - 2)
→ 4x - 5 = 6x - 6
→ 6x - 4x = -5 + 6
→ 2x = 1
→ x = 1/2
- if x is 1/2, then y: 2x - 2
→ 2(1/2)-2
→ -1
