Answer:
So we know that y=1/2x. So we apply this equation on each x.
x=-2, so y=1/2*-2 which is -1. so y = -1
x=0, so y = 1/2 * 0 which is 0. so y=0
x=2, so y = 1/2*2 which is 1. so y=1
Hope this helps :))
Answer:
Step-by-step explanation:
2x + 5y = 6 --------( 1 )
5x - 2y = 9 --------( 2 )
_____________
( 1 ) x 5 => 10x + 25y = 30 -----------( 3 )
( 2 ) x 2 => 10x - 4y = 18 ----------- ( 4 )
______________
( 3 ) - ( 4 ) => 0 + 29y = 12
Substitute y in ( 1 ) =>
Answer:
Step-by-step explanation:
Given equation:
Expand the left side:
Let all terms on the left side have the same denominator of 7:
Join the terms on the left side:
Let all the terms on the right side have the same denominator of 3:
Join the terms on the right side:
Cross multiply:
Expand:
Add 12x to both sides:
Add 252 to both sides:
Divide both sides by 40:
