Answer:
x= - 35 over 89
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

7
x−23+5x=18(x−1)

x+−23+5x=(18)(x)+(18)(−1)(Distribute)

x+−23=18x−1837
7
x−23=18x−18
Step 2: Subtract 18x from both sides.

7
x−23−18x=18x−18−18x
−89
7
x−23=−18
Step 3: Add 23 to both sides.
−89
7
x−23+23=−18+23

x=5
Step 4: Multiply both sides by 7/(-89).

Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).
A system of linear equations has one solution when the graphs intersect at a point...!
Answer:
Step-by-step explanation:
The angle containing y and 63 are vertically opposite. They are equal.
y + 23 = 63 Subtract 23 from both sides
y +23-23 = 63 - 23
Answer y = 40
