Answer:
x = 2
2x + 1 = -x +7 Add and subtract
3x = 6 divide
x = 2
Y=x-7 this is because you subtracted the x to both sides. Since y is a negative, you divide by -1 causing the -x to turn positive and the positive seven to be negative seven.
His total would be 58.50 then you multiply by .25 percent then you take 14.63 and subtract that from the total and you get 43.87
First you have to get rid of the mixed numbers, so multiply the whole numbers with the denominators and add the numerators so that way you get:
14/3 times 45/4....then cross simplify if possible and finally you can multiply the numerators and the denominators...
7/1 times 15/2 = 105/2....simplify it and get: 52 1/2
