Preciso com urgência

Answer 1

a) x-3=7
×=7+3
×=10
b)×+101=300
×=300-101
×=199
c)×-279=237
×=237+279
×=516
d)×-8=-10
×=-10+8
x=-2
e)×+9=-1
×=-1-9
-10
f)9×=18
x=18/9
×=2
g)35×=-105
x=-105/35
×=-3
h)7×-1=13
7×=13+1
7x=14
x=14/7
x=2
i)6×=2×+28
6×-2×=28
4×=28
x=28/4
x=7
j)6×-10=2×+14
6×-2×=14+10
4x=24
x=24/4
x=6

espero ter ajudado!
