Answer:
x = 2 and y = 7
Step-by-step explanation:
We are given two equations:
1. 8x + y = 23
2. −10x - y = −27
By adding both equations with each other we get:
(1.+2.) -2x = -4
Which can be reduced to:
(1.+2. : (-2)) x = 2
We can insert x in Equation 1. (or 2) and get:
8*2 + y = 23
16 + y = 23 [-16 on both sides]
y = 7
Resulting in x = 2 and y = 7 as a possible solution for this system.
Answer:
Step-by-step explanation:
8x + y = 23
-10x - y = -27
-2x = -4
x = 2
8(2) + y = 23
16 + y = 23
y = 7
(2, 7)
