The answer is 5/9
Hope this helps
You re write the equation, so when the equations are added one of the variables are eliminated
I'm pretty sure its A but it could be B
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation for example : -8-7x+-5(4)=0 . But the zero turned to -1 because a non zero constant never equals 0,but the problem doesn’t have a solution, but the answer is -1
B.) because according to the identity property of addition, any number added to zero will remain the same.
