What is the answer <br> y=2x+3<br> y=3x+5
Marizza181 [45]
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

  • Group like terms

4x + x + 10 = 180

  • Add: 4x + x = 5x

5x + 10 = 180

  • Subtract 10 from both sides

5x + 10 - 10 = 180 - 10

5x = 170

  • Divide both sides by 5

5x / 5 = 170 / 5

x = 34
