Substitute 5 for x and solve: 8 + 6(5) = ?
x/-5 + 8 = 11 To solve this: Subtract 8: x/-5 = 3 Multply by -5: x = 3*-5 Work it out: 3*-5 = -15 x = -15

you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
x2 - 16x + 68 = 5 (x - 8)2 + 4 = 5 (x - 8)2 = 1 x - 8 = 1 or -1 x = 9 or 7
x/5 = 8/21 x = 8/21 * 5 x = 1.904761905
Substitute 5 for x and solve: 8 + 6(5) = ?
8
5 + 8(3 + x) 5 + 24 + 8x 29 + 8x
x/-5 + 8 = 11 To solve this: Subtract 8: x/-5 = 3 Multply by -5: x = 3*-5 Work it out: 3*-5 = -15 x = -15

Let the number be x x/5 = 8 Multiply both sides by 5 to solve for x: x = 40
how do you solve 8+x=x+8
you just equal that equation to 0, then you solve for x 5x-8=0 5x=8 x=8/5
x2 - 16x + 68 = 5 (x - 8)2 + 4 = 5 (x - 8)2 = 1 x - 8 = 1 or -1 x = 9 or 7
8-5(2+x)=2(x+1)
Assuming the question is "solve for x", the answer is x=5
