Sagot :
-6=-7+x
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
Make the variable to the left hand side and change it’s sign.
-6-x=-7
Move the constant to the right hand side and change its sign.
-x=-7+6
Calculate the sum
-x=-1
Change the signs of both sides of the equation .
X=1
Answer : x=1
-3=-7+x/2
-3=-7+x/2
2(-3)=(-7+x/2)*2
-6 =-7+x
-6+7=x
x=1
More explanation
We multiplied both sides by 2 > is as same as (-7+x)*1/2
When we move -7 to the other side to -6 It changes the positive sign to -7
-3=-7+x/2
-3=-7+x/2
2(-3)=(-7+x/2)*2
-6 =-7+x
-6+7=x
x=1
More explanation
We multiplied both sides by 2 > is as same as (-7+x)*1/2
When we move -7 to the other side to -6 It changes the positive sign to -7
