She did everything correct in step 1 and 2
Until step 3 she took a wrong turn.
She wrote seven times x over seven = twenty-three over 7
When she should have wrote..
negative seven times x over negative seven = twenty-three over negative seven
So her answer was
23/7
while it should have been a negative. -> -23/7
Good Luck! :)
Yes good job you are correct
Answer:
The value of x is 2/3.
Step-by-step explanation:
The perimeter of a square is 4s.
Substitute the value and simplify.
4( 3x - 2 ) Distribute
12x - 8 In this case this is an equation
12x - 8 = 0 Add 8 on both sides
12x = 8 Isolate the variable by dividing 12 on both sides
x= 2/3
You must isolate the variable in order to solve equations with variables.
Isolating variable is basically when you divide, multiply, add, or subtract to put a variable on <em><u>ONLY </u></em>one side of the equation.
