Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3. that is
7x - 3 = 5x + 3 ( subtract 5x from both sides )
2x - 3 = 3 ( add 3 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Answer:
x = 3
Step-by-step explanation:
5x - 3 + 2x = 5x + 3
<em>subtract 5x from both sides</em>
5x - 5x - 3 + 2x = 5x - 5x + 3
-3 + 2x = 3
<em>add 3 to both sides</em>
-3 + 3 + 2x = 3 + 3
2x = 6
<em>divide both sides by 2</em>
2x/2 = 6/2
x = 6/2
x = 3

Answer:
- Take two points
- 64-18/97-29=23/34
- Now plug that into the equation to find the equation
- 97=23/34(29) +b
- B is the y intercept
- B= 77.38
- Hence the equation is y= 23/34(x) + 77.38
