We want to use the Substitution method to solve
7x - 2y = 1 (1)
x - 2y = 1 (2)
From equation (1), obtain
2y = 7x - 1 (3)
Substitute (3) into (2).
x - (7x - 1) = 1
-6x + 1 = 1
-6x = 0
x = 0
From (3), obtain
2y = 7*0 - 1 = -1
y = -1/2
Answer: (0, -1/2) or x=0, y= -1/2.
Answer:

im 99% that its correct
Answer:
Subtract 58 from both sides
Step-by-step explanation:
93 = x + 58
Subtract 58 from both sides
93- 58 = x+58-58
35 = x
The answer is 2/3 (i think ✨)
