How do you do 2x-7 equals 15?
2x - 7 = 15 2x = 22 x = 11
What is the answer to 4x-7 equals 2x plus 15?
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
What is -7 plus 2x equals x plus 8?
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
What is 5x 15 2x 7?
The expression "5x 15 2x 7" seems to be missing operators. If we interpret it as "5x * 15 * 2x * 7," then we can multiply the coefficients and the variable terms. The result would be ( 5 * 15 * 2 * 7 \cdot x^2 = 1050x^2 ). If you meant something different, please clarify!
What is x when f of x equals -7 and f of x is defined to be 2x plus 8?
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
How do you do 2x-7 equals 15?
2x - 7 = 15 2x = 22 x = 11
What is the answer to 4x-7 equals 2x plus 15?
4x - 7 = 2x + 15 4x = 2x +222x = 22x = 11
What is -7 plus 2x equals x plus 8?
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
What plus 7 = –15?
It is 2x - 8
How do you solve y equals 2x plus 15 and y equals 4x plus 7 using substitution?
y = 2x + 15 y = 4x + 7 Substitute the value of y from the first equation into the second: 2x + 15 = 4x + 7 Subtract 2x from both sides: 15 = 2x + 7 Subtract 7 from both sides: 8 = 2x Divide both sides by 2: 4 = x. Replace x by its value, 4, in the first equation: y = 2*4 + 15 = 8 + 15 = 23 So the solution is (x, y) = (4, 23)

What is the answer for 2x plus 8 plus x equals 2x plus 15?
2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7
What is 2x plus 8 plus x equals 2x plus 15?
X=7
What is 3x-x plus 7-15?
It is 2x - 8
The sum of what two consecutive whole numbers equals 15?
7 and 8. You know that the sum of any two consecutive whole numbers, x and x +1, is 2x +1 2x + 1 = 15 2x = 14 x = 7
What is x if 2x plus 7 equals 15?
Subtract 7 from each side of the equation: 2x = 8 Divide by 2: x = 4
