How many solutions does each equation have?
1 answer:
1.
2x-2=2x+32x-2=2x+3
notice
2x-3=2x+2
minus 2x both sides
-3=2
false
no solution
2. 5m-4=7m+85m-4
add 4 to both sides
5m=92m
therefor m=0
but wait
5m-4=7m+8
5(0)-4=7(0)+8
-4=8
false
no solution
3.
y+7=y-3
minus y both sides
7=-3
false
no solution
none of them have solutions

Answer: The answer is x=9
(PLEASE VOTE ME BRAINLIEST. I NEED TO LEVEL UP LOL)
The solution is a=4
-2(1+5a)=-6(a+3)
-2-10a=-6a-18
+18 +18
16-10a=-6a
+10a +10a
16=4a
divide by 4
4=a
