Question

Help pls??

Solve for x: -3(x + 3) = -3(x + 1) - 5.

Answer 1

Distribute first.

Answer 2

First what you have to do is distribute whatever is outside the parenthesis to whatever is inside the parenthesis.

Answer 3

ok so it would be -3x-9=3x-3-5?

Answer 4

question is wrong if we are to find x.. i guess

Answer 5

yes, that is correct so far

Answer 6

ok so after that would it be -3x-9=-3x-8?

Answer 7

-3x on both sides gets cancelled .. isn't it?

Answer 8

im so confused after that

Answer 9

i think either on LHS or RHS there should not be a negative sign..

Answer 10

@maryta36 yes thats right. then you move the numbers without variables to one side. For example, in your equation, you may want to add -8 to both sides. which would cancel out-8, and add it to -9.

Answer 11

so it would be -1?

Answer 12

actually it would be -1=0. Because there is nothing more that you can do to the equation. Thats right!

Answer 13

a) 6

b)-6

c)All real numbers

d) No solution


so it would be no solution right ? so D?

Answer 14

yep

Answer 17
