Answer:
(2, 0)
There is one solution
Step-by-step explanation:
Given the set of equations
x+y = 2
2x+y = 4
Substract both equations
x - 2x = 2 - 4
-x = -2
Multiply thrugh by -1
-1(-x) = -1(-2)
x = 2
Substitute x = 2 into equation1 ;
From 1, x+y = 2
2 + y = 2
y = 2-2
y = 0
hence the solution to the system of equation is (2, 0). Hence there is only one solution

Answer:
x = 26
Step-by-step explanation:
m<RTS = 4x - 14 (given)
Based on the inscribed angle theorem, the measure of the inscribed angle in a semicircle = right angle (90°)
Therefore,
4x - 14 = 90
4x - 14 + 14 = 90 + 14 (addition property of equality)
4x = 104
4x/4 = 104/4
x = 26
