To solve the equation 2X+8=X+10 the first step is to get all instances of the variable 'X' on the same side of the 'equals' sign. To do this, we must first subtract 'X' from both sides of the equation:
2X+8-X=X+10-X which then becomes X+8=10. The next step is to leave the variable 'X' alone on it's side of the 'equals' by subtracting the numeral 8 from both sides of the equation:
X+8-8=10-8 which then becomes X=2.
To confirm that the solution is correct, we then substitute the solution we arrived at into the original equation in place of the variable 'X':
2*2+8=2+10
2*2=4 so:
4+8=2+10
4+8=12 and
2+10=12 so the final solution is:
12=12
Therefore the answer to the question "Is 2X+8 equal to X+10" is Yes, and the value of the variable 'X' is 2
16 + 2x = 10 + 8x 2x - 8x = 10 - 16 -6x = -6 x = 1 Check: 16 + 2(1) = 10 + 8(1) 18 = 18
2x + 30 = 4x + 22 Subtracting 2x from both sides, 30 = 2x + 22 Subtracting 22 from both sides, 8 = 2x Dividing both sides by 2, 4 = x x = 4
8
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
2X + 4Y = 8 The Y-intercept is the place where the line described by the equation crosses the Y-axis. But X=0 everywhere on the Y-axis. So at that point, 4Y = 8, and Y = 2. The X-intercept is the place where the line described by the equation crosses the X-axis. But Y=0 everywhere on the X-axis. So at that point, 2X = 8, and X = 4.
-2x + 8 = 7x - 10 is technically an equation, in and of itself.
2x+8=10... Subtract 8 on both sides, then devide by 2... 2x=2... x=1
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
if it is -X then X=5 if it was minus X the X=10
An equation, solution x = -10
2y = -10y = -58 - 2x - 2(-5) = -108 - 2x + 10 = -10-2x = -10 - 182x = 28x = 14Check:2y = 8 - 2x - 2y = -102(-5) = 8 - 2(14) - 2(-5) = -10-10 = 8 - 28 + 10 = -10-10 = -20 + 10 = -10-10 = -10 = -10
8 - 10 + 7 = 5 x = 4
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 = 5x+10 Take 3x away from both sides: 8 = 2x + 10 Take 10 away from both sides: -2 = 2x Divide both sides by 2: -1 = x
X=7
