Answer:
angle 1 = 135 degrees
Step-by-step explanation:
Unknowns on one side, known on other.
2/5x - 4/5x = 30-25
-2/5x=5
X= -25/2
X=12.5
Answer:
x = 1, y = 4
Step-by-step explanation:
This is very simple
Since you have 2 equations with the same coefficient of x, just minus one equation from another:
x + 3y = 13
-
x + 2y = 9
1y = 4
Sub y = 4 into any of the 2 equation,
x + 3(4) = 13
x + 12 = 13
x = 13 - 12
= 1
