We can use substitution.
We can substitute 2x + 3 for 'y' in the 2nd equation.
y = 3x + 5
2x + 3 = 3x + 5
Subtract 3 to both sides:
2x = 3x + 2
Subtract 3x to both sides:
-x = 2
Multiply -1 to both sides:
x = -2
Now we can plug this into any of the two equations to get our y-value:
y = 2x + 3
y = 2(-2) + 3
y = -4 + 3
y = -1
So our solution is (-2, -1)
Answer:
X = 78, Z = 29, and Y = 102
Step-by-step explanation:
X = 78. 43 + 59 = 102. There has to be 180 degrees in a triangle. So subtract 180 by 102.
Z = 29. Think of the whole triangle for this one. 43 + 49 + 59 = 151. 180 - 151 = 29.
Y = 102. Plug in the value of Z. 49 + 29 = 78. 180 - 78 = 102.
Hope that helps!
Answer:
<h2><u>Supplementary</u></h2><h2><u>x = 34</u></h2>
Explanation:
- Supplementary angles: Angles that measure up to 180°
- Write an equation to find x
4x + 10 + x = 180
4x + x + 10 = 180
5x + 10 = 180
- Subtract 10 from both sides
5x + 10 - 10 = 180 - 10
5x = 170
5x / 5 = 170 / 5
x = 34
