Answer:
x = -1
Step-by-step explanation:
<u>Step 1: Distribute</u>
-5(x + 2) = -(-5x + 1) - x
-5x - 10 = 5x - 1 - x
<em>-5x - 10 = 4x - 1</em>
<em />
<u>Step 2: Solve for x</u>
-5x - 10 + 5x = 4x - 1 + 5x
-10 + 1 = 9x - 1 + 1
-9 / 9 = 9x / 9
<em>-1 = x</em>
<em />
Answer: x = -1
Answer:
-5 =x
Step-by-step explanation:
f(x)=x+5
Set the function equal to zero
0 = x+5
Solve for x
-5 = x+5-5
-5 =x
Answer:
26
Step-by-step explanation:
Because DAC is a straight line we can equate that:
4x - 8 + 34 + 76 - x = 180
3x + 102 = 180
3x = 78
x = 26
