Step-by-step explanation:
3x-24=-2
3x=-2+24
3x=22
x=22÷3
x=7.333
Set the equations to equal each other:
-2x²+1=-2x+1
Solve for x:
-2x²+1=-2x+1
-2x²+2x+1=-2x+2x+1
-2x+2x+1-1=1-1
-2x²+2x=0
2x (-x+1)=0
2x=0 and -x+1=0
2/2x=0/2 -x+x+1=0+x
x=0 1=x
There are two solutions, x=0,1

IT IS BETTER TO USE A COMPUTER BECAUSE IN TEXTBOOKS U DONT GET MUCH INFORMATION AS YOU DO IN A COMPUTER
<u>Step 1:</u> We have the next system of equations -
<u>Step 2:</u> Now, we will multiply by -2 the second equation:-
<u>Step 3:</u> Then we add it :-
<u>Step 4:</u> After finding the sum, we simplify:-
Then, substitute the above <em>y </em>value to find x's value in any equation of Step 1. Now, I used to second equation in Step 1:-
<u>Step 5:</u> Then simplify :-
Therefore, the final answer is :-
