Answer:
x = -3
Step-by-step explanation:
-8x - 18 + 7 + 2x = 5 - 3x - 4 + x
-8x + 2x + 3x - x = 18 - 7 + 5 -4
-4x = 12
x = -3
Answer:
9
Step-by-step explanation:
Let x represent the number of ₹50 notes. Then the number of ₹10 notes is (x+1) and the total value of all notes is ...
₹50·x + ₹10·(x+1) = ₹550
₹60·x = ₹540 . . . . . . . . . . . . subtract ₹10 and collect terms
x = 9 . . . . . . . . . . . . . . divide by ₹60
The number of ₹50 notes is 9.
24.5= <span><span>−<span>2.5c</span></span>−<span>4<span>c
</span></span></span><span>24.5=<span><span><span>−<span>2.5c </span></span>+ </span>−<span>4c</span></span></span><span>24.5 = <span>(<span><span>−<span>2.5c</span></span>+<span>−<span>4c</span></span></span>) </span></span><span>24.5=<span>−<span>6.5c </span></span></span><span>24.5=<span>−<span>6.5<span>c
</span></span></span></span><span>−<span>6.5c</span></span>=<span>24.5
</span><span><span><span>−<span>6.5c </span></span><span>− 6.5 </span></span>=<span>24.5 <span>− 6.5 </span></span></span><span>c=<span>−<span>3.769231
These are all the steps that you do to solve this equation. I worked it out fully and the answer is above these words.</span></span></span>
