5x + 3 = 38
5x = 38-3
5x = 35
x= 7
The last number will either be 5 or 0. For example 15, or 20.
(x,y) = (1, 1.2)
1 = 7(1) - 5(1.2)
1 = 7 - 6
There are many other options though.
Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
10x + 2 is an exterior angle of the triangle, thus
10x + 2 = 2x + 1 + 25
10x + 2 = 2x + 26 ( subtract 2x from both sides )
8x + 2 = 26 ( subtract 2 from both sides )
8x = 24 ( divide both sides by 8 )
x = 3
