Answer:
y=3x+1
Step-by-step explanation:
if im correct you are working on elimination, so you pretty much sub. so the difference between -2 and 3 is positive 1; the difference between 4x and x is 3x
are you working on elimination?
There is no solution to this set that works for both equations. If you multiply the top equation by 2 and then add them together, the x and y numbers will cancel. This leaves you with 0 =1010, which is never true.
-25=-4r+5
Subtract 5 to each side
-25-5=-4r+5-5
-30=-4r
Divided -4 to each side
-30/-4=-4r/-4
7.5=r
Check:
-25=-4r+5
Substitute r with 7.5
-25=-4(7.5)+5
-25=-30+5
-25=-25. As a result, r=7.5. Hope it help!
Answer:
