Answer:
(-2, 1)
Step-by-step explanation:
Systems of equations can be solved using different methods. For this set of systems, you can multiply each equation by a factor in order to eliminate a variable and solve for the other variable:
-3(-5x - 3y = 7) or 15x + 9y = -21
5(-3x - 4y = 2) or <u>-15x -20y = 10</u>
-11y = -11
y = 1
Solve for x: -5x - 3 = 7
Add 3 to both sides: -5x -3 + 3 = 7 + 3 or -5x = 10
Solve for x: x = -2
(-2, 1)
Erotically angles are opposite each other and equal the same degree.
In the image 5x and 120 are vertical angles so 5x needs to equal 120.
X = 120/5
X = 24
Answer:
C
Step-by-step explanation:
the answer for this question is
-2 and 6
If you take 438 divided by 4 = 109.5 109.5 + 74.5 = 184 74.5 x 4 = 298
