Solve the equation for 3x-y = -3

Mathematics
1 answer:
S_A_V [24]2 years ago
8 0

Answer:

sln

3x-y=-3

3x-y=-3(make subject x)

3x=-3+y(divided by 3 both sides)

x=(-3+y) /3,x=-1+y /3

find y

3x-y=-3

-y=-3-3x(put the value of x)

-y=-3-3(-1+y/3)

-y=-6(-1+y/3)

-y=6+y/3

-y-y/3 =-3

-4y/3=-3(X by 3 both sides)

--4y=-6(divided by - 4 both sides)

y=1.5

find x

3x-y= -3 (put the value of y)

3x-1.5= -3

3x=-3+1.5

3x=-1.5(divided by 3 both sides)

x=-0. 5

A − 7 = 3 (b+2) pls answer soon
Alexeev081 [22]
I believe the answer is....

For solving for a

a-7= 3(b+2) ———> distribute 3(b+2)
a-7= 3b+6 ———-> add 7 on both sides

a-7= 3b+6
a+7= 3b +7 ———-> the 7’s cancel out so you’re left with....

a = 3b + 13 (That’s your answer)

Hope that helped :3
