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 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

If x equals 4 then 2x plus 7 equals?
If x=4 then 2x+7 =
8x-7 plus 2x equals 6 plus 5x plus 2?
8x-7 plus 2x equals 6 plus 5x plus 2?
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 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)
