Substituiotion method to find the value of y y equals 2x plus 5 x plus y equals 4?
y = 2x+5 x+y = 4 Substitute the value of y into the second equation: x+2x+5 = 4 x+2x = 4-5 3x = -1 Divide both sides by 3 to find the value of x: x = -1/3 Substitute the value of x into the original equations to find the value of y: x = -1/3 and y = 4 and 1/3
What does 0 divide by x equal?
0 ÷ x = 0 (unless x is known to have the value zero, as you cannot divide by zero).
What times 5 equals 400?
To find what times 5 equals 400, you can set up the equation as x * 5 = 400. To solve for x, you would divide both sides of the equation by 5, giving you x = 400 / 5. Therefore, the value of x that satisfies the equation is x = 80.
If 12x equals 4 parenthesis x plus 5 parenthisis what does x equal?
12x = 4(x+5) 3x = x+5 divide by 4 2x = 5 subtract x x = 2.5 divide by 2
What is an equivlent fraction is 5-6 and 10-12 equivlent why or why not?
5/6 = 10/12 because 10/12 is 5/6 x 2/2, which is the same as multiplying 5/6 x 1 so it doesn't change its value. If you divide 5 by 6 you will get the same answer as you do if you divide 10 by12.
