Answers

Answer:

2x + 60 = 4x( Vertically opposite angle)

60 = 4x - 2x

4x - 2x = 60

2x = 60

x = 60÷2

x = 30

2x + 60 + B = 180° ( Linear Pair )

2(30) + 60 + B = 180°

60 + 60 + B = 180°

120 + B = 180°

B = 180° - 120

B = 60

I will give brainliest away if you solve this for me please.

Answers

Turn both equations into slope-intercept form [ y = mx + b ].

x + 3y = 3

~Subtract x to both sides

3y = 3 - x

~Divide 3 to everything

y = 1 - x/3

~Reorder

y = -1/3x + 1

4x + 3y = -6

~Subtract 4x to both sides

3y = -6 - 4x

~Divide 3 to everything

y = -2 - 4x/3

~Reorder

y = -4/3x - 2

Graph of the equations will be shown below. Note that the solution of graphing two equations will be where both equations intersect. Both lines intersect at (-3, 2), hence making that the solution.

Best of Luck!
