We can answer this question by solving each equation for one variable, and then substituting.
3x + y = 11 Given
y = -3x + 11 Subtract 3x from both sides
This equation is now solved for y. Now, let's do the other equation. Make sure to solve it for the same variable.
-2x + y = 1 Given
y = 2x + 1 Add 2x to both sides
Now, let's set both equations equal to each other, since they both equal y.
2x + 1 = -3x + 11 Set both equations equal to each other
1 = -5x + 11 Subtract 2x from both sides
-10 = -5x Subtract 11 from both sides
2 = x Divide both sides by -5
Now, let's substitute x in for one of the equations we found earlier, so that we can find y.
y = 2x + 1 Given
y = (2)(2) + 1 Substitute the x-value, 2
y = 4 + 1 Multiply
y = 5 Add
So, x = 2 and y = 5.

sorry if i didnt do it right
Step-by-step explanation:
As these two triangles are similar we know a few things:
Their respective angles will have the same measure
Their respective sides will be proportional to each other.
Knowing this, we can sole for x by creating a proportion of the two given sides
Now we can solve for x
Knowing that the respective angles will be equal we can create this equation to solve for y
And knowing that, again, the angles will be equal to each other If we solve for angle E, we can know the measure of angle H
We are given two of the angles of GEF and the sum of the angles of a triangle is always 180. We can setup an equation as follows
