Answer:
y =2.5
Step-by-step explanation:
1.4y = 3.5
Divide each side by 1.4 to isolate y
1.4y /1.4 = 3.5/1.4
y =2.5
here,
2x-6y= -12
2(x-3y)= -12
x-3y = -6...........eq1
x+2y=14............eq2
we can subtract the above two given equations
we get,

___________

so,
y=4
now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2
we get,

<h3>so,</h3><h3> x=6,y=4</h3>
