This is the equation made from the problem where x=mystery number 2x+3(x+1)=4(x-1)
Now let's solve for x!
We start by distributing 3 into (X+1) 3(x)=3x and 3(1)=3 Now our equation is 2x+3x+3=4(x-1) Let's combine both x values on the left side of the equation: 2x + 3x=5x We now have 5x+3=4(x-1) Let's distribute 4 into (x-1) 4(x)=4x and 4(-1)=-4 Now our equation is 5x+3=4x-4 subtract 3 form both sides 5x=4x-7 subtract 4x from both sides x=-7 Yay! So the number she is thinking of is -7!
The number is -7. ;
Pasha is thinking of the number -7. We set the equation based on the problem's conditions and solved for x, confirming the solution with a check. The verification process shows both expressions equal -32 when x = -7.
