solve for x
show steps

Note the equal sign. What you do to one side, you do to the other.

Follow PEMDAS.

First, distribute -3 to all terms within the parenthesis.

-9 = -3(x + 2)

-9 = -3x - 6

Next, do the opposite of PEMDAS. Isolate the x. Note the equal sign. What you do to one side, you do the other.

Add 6 to both sides

-9 = -3x - 6

-9 (+6) = -3x - 6 (+6)

-9 + 6 = -3x

-3x = -3

Isolate the x. Divide - 3 from both sides

-3x/-3 = -3/-3

x = -3/-3

x = 1

1 is your answer for x

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
