Answer:
x = -1 and y = 6
Step-by-step explanation:
y = x + 7
5x + 2y = 7
y - x = 7.............(1)
2y + 5x = 7......(2)
multiply equation (1) by 2
2y - 2x = 14
2y + 5x = 7
subtract equation (2) from (1)
2y - 2x = 14
- 2y + 5x = 7
-------------------
0 -7x = 7
-7x = 7
divide both sides by 7
-7x = 7
----- ----
7 7
-x = 1 multiply through by minus sign
x = -1
substitute x = -1 into equation (1)
y - x = 7
y - (-1) = 7
y + 1 = 7
y = 7 - 1
y = 6

Hey there!
Now, let's look into figure.
angle ACB = 65° { Base angle of triangle ABC}
angle ACB + angle BAC + angle ABC = 180°
65° + 65° + angle ABC = 180°
angle ABC = 180°-130°
Therefore, angle 50°
angle EBD = 50° ( Vertically opposite angle)
Now;
angle EBD= angle DEB = 50° ( Base angle of triangle BDE )
angle BDE + angle DEB + angle EBD = 180° ( Sum of interior angle)
angle BDE = 180° -100°
Therefore, angle BDE = 80°.
Now, 80° + 14x + 2 = 180° { being linear pair}
14x = 180°-82°
14x = 98°
X = 7°

So, the equation was: 2 2/5* 4 1/2 - 5 ^3+3
The answer is: -111 1/5 (In decimal form, this is equivalent to -111.2 In case that is relevant.)
Simplifying this equation, if you didn't, I got (2 2/5) (4 1/2) - 5^3 + 3
Solving this step-by-step, I got the answer -111 1/5 (As stated above)
Step-by-step:
Step 1: Write equation (2 2/5) (4 1/2) - 5^3 +3 =
Step 2: 12/5 (4 1/2) - 5 ^3 + 3 =
Step 3: 12/5 (9/2) - 5^3 +3 =
Step 4: 54/5 - 5^3 +3 =
Step 5: 54/5 - 125 + 3 =
Step 6: -571/5 +3 =
Step 7: -556/5 which is equivalent to -111 1/5
I think that, overall, if you had issues with this, it was just the simplification.
Hope this helps.
