<h2>y = -4</h2><h2>x = -2</h2>
<h2>________________________</h2>
Step-by-step explanation:
y = 2x
<h3>y÷2 = x</h3>
<h2>------------------------------------------</h2>
so,
3x + 3y = -18
3(y÷2) + 3y = -18
3y ÷2 + 3y = -18
( 3y + 6y )÷2 = -18
9y ÷2 = -18
9y = -18 ×2
9y = -36
<h3>y = -4</h3>
<h2>-----------------------------------------</h2>
x = y÷2
x = -4÷2
<h3>x = -2</h3>
<h2>follow me</h2>
Answer:
x=-2,y=-4
Step-by-step explanation:
Substuting the value of y in second equation.
3x+3×2x=-18
9x=-18
x=-2
putting the value of x in equation 1 ,
y=-4
