When you are solving equations like this, you simply need to remember to combine like terms and isolate the variable to one side or the other.
1. 2x-17=4 (Add 17 to both sides....the left cancels out the -17)
2x= 21 (divide both sides by 2)
x = 10.5
2. (10x+5) + (6x-1) = 180 (combine like terms....the parentheses are there to just group them into different terms)
16x+4 = 180 (subtract 4 from both sides)
16x = 176 (divide each side by 16)
x = 11
3. 3x + 4 = 2x - 1 (isolate the variable to one side, let's go with the left and subtract 2x from both sides)
x + 4 = -1 (subtract 4 from both sides)
x = -5
4. <span> 2(x + 4) = x + 13 (apply the distributive property to the parentheses)
2x + 8 = x + 13 (isolate the variable to the left side and subtract x)
x + 8 = 13 (subtract 8 from both sides)
x = 5
</span><span>5. 14x = 2(5x + 14) (apply distributive property to the right side)
</span> 14x = 10x + 28 (isolate the variable to the left, subtract 10x)
4x = 28 (divide both sides by 4)
x = 7
Hope all the steps are clear and you can see why each step was taken. Good luck!
Answer:well you see this is easy first you look at the 113 divide that by 4 multiply by 2 and then square root and you have your answer which would be d <4
Step-by-step explanation:
The bottom answer, as the x coordinate of c to c’ is five across
Answer:
<h2>
x = -3, y = -7</h2>
Step-by-step explanation:
-5x + 7y = -34 ⇒ -5x = -34 - 7y
-5x + 3y = -6
-34 - 7y + 3y = -6
-34 - 4y = -6 {add 34 to both sides}
-4y = 28 {divide both sides by (-4)}
y = - 7
-5x + 3y = -6
-5x + 3(-7) = -6
-5x - 21 = -6 {add 21 to both sides}
-5x = 15 {divide both sides by (-5)}
x = -3
