We need to solve for x, we need to get x alone
Lets start by removing -5
Add 5 on both sides
Now to isolate x , we need to remove the square from x
To remove square , take square root on both sides
square and square root will get cancelled
So and
Answer:
Step-by-step explanation:
- x/7<-3
- x<-3x7
- x<-21
Using elimination, we add the equations, but this time from left to right. This process wants to elimination a variable. So 2x plus -2x equals 0. Moving on the next variable, 6y plus -y is 5y. On to the last variable, 18 plus 12 is 30. So we have this equation, 5y=30. 30/5 is 6, so y=6. We plug 6 into y in one of the equations you choose. In this case, I'm going to use the first equation. Plugging 6, we have this equation, 2x plus 36 is 18. 18-36 is -18. We then have this equation, 2x=-18. We know -9 times 2 is -18, so our x value is -9, So, our y=6, and our x=-9.
Option 3 (1/4 x 60) since 59 is close to 60 and 25% can be rewritten as 1/4
Answer:
B) X = 90
Step-by-step explanation:
If you plug in every answer choice as "X," you can easily find which answer helps the equation equal 40.
EX. 1/2 (or 0.50) times 90 plus -4 equals 41!
Equation with "X" filled in as 90 :
41 = 1/2 x 90 + (-4)!!!
Now can I get brainliest!!??
