Answer:
Step-by-step explanation:
Example 1 Determine if the value 3 is a solution of the equation
4x - 2 = 3x + 1
Solution We substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member.
4(3) - 2 = 3(3) + 1
12 - 2 = 9 + 1
10 = 10
Ans. 3 is a solution.
Answer:
2x-y=8
Step-by-step explanation:
Equation of a line y-y1 =m(x-x1)
Given m=2, x1=7, y1=6
y-6 = 2(x-7)
y-6 = 2x-14
2x-y = 8
