-7 +2x = x + 8 2x - x = 7 + 8 x = 15
yes
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
2x + 8 + x = 2x + 15 simplify 2x to both sides since they have the same sign8 + x = 15 subtract 8 to both sidesx = 7
-7 +2x = x + 8 2x - x = 7 + 8 x = 15
yes
no x would be 0.5 because two times 0.5 is 1 ( 2x ) and then add 7 equals 8 ( plus seven equals 8 )
2x + 8 = x - 7Subtract 'x' from each side of the equation:x + 8 = -7Subtract 8 from each side:x = -15
2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
f(x) = 2x + 8 f(x) = -7 → 2x + 8 = -7 → 2x = -15 → x = -7½ = -7.5
6x - 8 + 2x - 5 = 7 - 2x ?
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
-5x+3(x+8)=16-2x
Subtract 7 from each side of the equation: 2x = 8 Divide by 2: x = 4
