Let's get the same terms on the same side.
I am going to remove 5x from both sides of the equation by subtracting 5x
5x - 5x<span> -7 = 7x -</span>5x<span> - 17</span>
-7 = 2x - 17 now lets remove the 17 from both sides
-7 + 17 = 2x (why do we add 17? Think of 2x -17 as 2x + -17. Tor remove a negative number we add it.
Now we finally have 10=2x and if we divide both sides by 2
<u>10</u><span> = </span><u>2x</u><u>
</u>2 2 we get that x = 5
<u />Let's check by substituting 5 in the original equation:
5(5) - 7 = 7(5) - 17
25 - 7 = 35 - 17
<span>18 = 18</span>
Answer:
1562.5
Step-by-step explanation: 2500 divided by 8 times 5
Answer is 4 X(x+5)=36
X^2+5x-36=0
(X+9)(X-4)
X+9=0. X-4=o
X=-9. X=4
Answer:
x=25 degrees
Step-by-step explanation:
x= 90 degrees - given(65 degrees)
x=90-65
x=25 degrees.
The angles add up to 90 degrees.
