Answer:
x = 27
Step-by-step explanation:
1. Combine like terms
<u>135 + 120</u> +<em> 3X </em><u>+ 31 </u><em>+ 4X </em><u>+ 15</u><em>+ 6X</em><u> -8</u><em> + 7X </em><u>-64 </u><em>+ 5X</em><u> -4 </u>= 900
135+120+31+15-8-64-4=225
3+4+6+7+5=25X
2. Replace into the equation
25X + 225 = 900
3. Subtract 225 from both sides of the equal sign
25X = 900 - 225
4. Combine like terms
25X = 675
5. Divide each side of the equal sign by 25 to get X by itself
X = 27
5.0625
Step-by-step explanation:
Step 1:
The given expression can be written as
![135X + 120 + 3X + 31 + 4X + 15+ 6X -8 +7X-64 +5X-4 =900](https://tex.z-dn.net/?f=135X%20%2B%20120%20%2B%203X%20%2B%2031%20%2B%204X%20%2B%2015%2B%206X%20-8%20%2B7X-64%20%2B5X-4%20%3D900)
On solving the above expression
adding all the X terms and constant terms individually
160X + 90 = 900
Step 2:
160X = 810
X = (810/160) =5.0625

The answer to your question is true
Answer:
there is no solution for these linear equations in two variables.
since a1 (y) = a2 (y)
b1 (5x) = b2 (5x)
but, c1 (12) not equal to c2 (18)
365.75 because you have to subtract everything from 550
