Answer x=5, y= 3.5

Find y by plugging the x value into the 2nd equation
4(2y-2) -9=11
8y - 8 - 9 =11 combine like terms
8y = 28 divide both sides by 8
y = 3.5

Now find x
Plug your y value into first equation
X = 2(3.5) -2
X= 7-2
X=5

You can check your work by putting your x or y values into the equations

For the first equation
5=2(3.5) -2
5=5

For the second equation
4(5) -9 = 11
20 - 9 = 11
11 =11

X = 2y-2 4x-9 = 11 Step by step please-example-1
