Question

a+123=2000
b+123=1123
c+1634=9830
d+63=194
x-120=300
y-60=1290
z-150=550​

Answer 1

$\mathbf{a+123=2000}$

$\mathbf{a=2000-123}$

$\boxed{\mathbf{a=1877}}$

$\mathbf{b+123=1123}$

$\mathbf{b=1123-123}$

$\boxed{\mathbf{b=1000}}$

$\mathbf{c+1634=9830}$

$\mathbf{c=9830-1634}$

$\boxed{\mathbf{c=8196}}$

$\mathbf{d+63=194}$

$\mathbf{d=194-63}$

$\boxed{\mathbf{d=131}}$

$\mathbf{x-120=300}$

$\mathbf{x=300+120}$

$\boxed{\mathbf{x=420}}$

$\mathbf{y-60=1290}$

$\mathbf{y=1290+60}$

$\boxed{\mathbf{y=1350}}$

$\mathbf{z-150=550}$

$\mathbf{x=550+150}$

$\boxed{\mathbf{z=700}}$
