Use substitution to solve the system of equations<br> Y+x=3<br> Y=1.5x+1
Serjik [45]

The solution to given system of equation is (x, y) = (0.8, 2.2)

<em><u>Solution:</u></em>

<em><u>Given system of equations are:</u></em>

y + x = 3 --------- eqn 1

y = 1.5x + 1 ---------- eqn 2

We have to solve the above system of equations by substitution method

<em><u>Substitute eqn 2 in eqn 1</u></em>

1.5x + 1 + x = 3

Combine the like terms

2.5x + 1 = 3

Move the constants to Right hand side of equation

2.5x = 3 - 1

2.5x = 2

x = 0.8

<em><u>Substitute x = 0.8 in eqn 2</u></em>

y = 1.5(0.8) + 1

y = 1.2 + 1

y = 2.2

Thus the solution to given system of equation is (x, y) = (0.8, 2.2)

Pt 2) Just find the measure
Radda [10]

Step-by-step explanation:

<YOZ = 60°

When two lines intersect each other, then four angles are formed. The angles that are opposite to each other at the intersection point are known as <em>vertically</em><em> </em><em>opposite</em><em> </em><em>angles</em><em>.</em><em> </em>VERTICALLY OPPOSITE ANGLES ARE ALWAYS EQUAL.

If < VOX = 90⁰, then <VOW = 60⁰.

<VOW and <YOZ are vertically opposite angles.
