Question

11. Solve the equation 3x - 1 = x + 7 and represent
the solution(s) on (1) the number line (2) the
Cartesian plane,​

Answer 1

Step-by-step explanation:

3x-1=x+7

3x-x=1+7

2x=8

x=4

value of y=0

3x-1+0y=x+7(4,0)

If y=1,x=

3x-1+0×1=x+7

3x-1+0=x+7

3x-x=7+1

x=4(4,1)

If y=2,x=

3x-1+0×2=x+7

3x-1+0=x+7

3x-x=7+1

x=4(4,2)
