The process of solving equation 16 minus 49x with square equal to 0

The original equation is: 16-49x ^ 2 = 0
All items are multiplied by (- 1) to make the coefficient of x ^ 2 positive (+)
49X^2-16=0.
Move - 16 to the right of the equal sign
49x^2=16.
Divide each item by 49 to get:
x^2=16/49.
Because both sides of the equal sign are positive numbers, it can be squared
√(x^2)=√(16/49)
x=±4/7.
∴ x1=4/7；
x2=-4/7√
Empirically, X1 = 4 / 7 and X2 = - 4 / 7 are the solutions (roots) of the original equation

Solve the equation 1 / 7 + X + 2 / 3 = 2 and 21 / 17

1/7+x+2/3=55/17
The solution is: x = 55 / 17-1 / 7-2 / 3 = 866 / 357

To solve the equations: 2x3 + 3y4 = 1712x6 − y2 = − 13

The equations are sorted out as follows: 8x + 9y = 17, ① x − 3Y = − 2, ②, ① + ② × 3: 11x = 11, that is, x = 1, substituting x = 1 into ② to get: y = 1, then the solution of the equations is x = 1y = 1
