150=25x. so you have to isolate the variable, x, by doing the opposite operation of multiplication, which is division. Divide 25 by 25, you cancel out, making you divide 150 by 25, your answer being 7. You could also count like quarters, 25 cents each.
X (x - 25) So X = 0 Or X = +25
32 + x = 259 + x = 25x = 25 - 9x = 16
Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.
25x + 75 = 25*(x + 3)
The answer is all the points on the line defined by 25x - 12y = 1
25x-32 = 7 25x-9 = 7 25x = 7+9 25x = 16 x = 16/25
X (x - 25) So X = 0 Or X = +25
32 + x = 259 + x = 25x = 25 - 9x = 16
5y=25x 25x=5y -5y 25x-5y=0
Using algebra to solve this problem (12 + .25x = 30), the answer (x) is 72.
25x + 75 = 25*(x + 3)
The answer is all the points on the line defined by 25x - 12y = 1
25x = 11 so x = 0.44
.25x+3=10 .25x=7 25x=700 x=28
25x (square) plus 40 plus 15 equals 680.
25 to 150 = r to 75 25/150 = 1/6 1/6 times 75 equals r.
You would formulate this problem X/100 * 150 = 72 and solve for X.
