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.

What are the steps for 5 times x plus 5 equals 20?
5x+5 = 20 Subtract 5 from both sides: 5x = 15 Divide both sides by 5 to find the value of x: x = 3
What is the value of x if 8x plus 5 equals 25?
8x + 5 = 25(- 5 from both sides)8x = 20(divide both sides by 8)x = 2.5
What is the value of x in the equation 3x + 7 = 22?
3x + 7 = 22 Subtract '7' from both sides Hence 3x = 15 Divide both sides by '3' x = 5 The answer !!!
What is 5 percent of 3 million?
remember: ''is value'' over ''of value'' equals ''%'' over ''100'' is/of = %/100 --------> x/3,000,000 = 5%/100 (cross cancel)100x = 15,000,000 ( divide both by 100 to get x by itself)x = 150,000
Why is x8 and x2 is x6 and not x4?
To divide indices you subtract, hust like to multiply you add. eg 5 to the sixth divide by 5 to the fourth is five to the (6 - 4) ie 5 squared ie 25. Check it : 5 to the sixth = 5 x 5 x 5 x 5 x 5 x 5; 5 to the fourth = 5 x 5 x 5 x 5; To divide 5 x 5 x 5 x 5 cancels out leaving 5 x 5.
