Hey there!
First lets add by the number 10 on each of your sides of the problem
Like: -5x - 10 + 10
= 10 + 10
Second lets divide by a -5 because both numbers equals to that number
Like: -5x / -5 (cancel )
20/-5
x = -4
Good luck on your assessment and enjoy your day

The gcf is 17 so 17(2x +y) I think
The right answer for the question that is being asked and shown above is that: "D.The z-statistic lies outside the critical region." Weston completed a hypothesis test and found that he could not reject the null hypothesis. A valid reason for his conclusion is that D.The z-statistic lies outside the critical region.
Simplify both sides of the equation
3x+1/10 = x+ -1/7
Subtract x from both sides
3x+1/10 -x = x+ -1/7 -x
2x+1/10 = -1/7
Subtract 1/10 from both sides
2x+1/10 - 1/10 = -1/7 -1/10
2x= -17/70
Divide both sides by 2
2x/2 = -17/70/2
x= -17/140
decimal x will equal -0.121
