how to solve two equation with 2 variables

how to solve these two equations :

sin(x2) +2x2 =0

sin(x1-1)+2(x1-1)=0

Answer 1

You could use fsolve or fminsearch

fun=@(x) [sin(x(2))+2*x(2); sin(x(1)-1)+2*(x(1)-1)];

[x,fval]=fsolve(fun,[0;0])

Equation solved.

fsolve completed because the vector of function values is near zero
as measured by the value of the function tolerance, and
the problem appears regular as measured by the gradient.

x = 2×1

1 0

fval = 2×1

0 0

[x,fval]=fminsearch(@(x) norm(fun(x)), [0,0])

x = 1×2

1.0000 -0.0000

fval = 9.4426e-05
