Emily is solving the equation 2(x+9)=4(x+7)+2 where did she make an error
1 answer:
Hello!
2(x + 9) = 4(x + 7) + 2
Distribute the 2
2x + 18 = 4(x + 7) + 2
Distribute the 4
2x + 18 = 4x + 28 + 2
Combine like terms
2x + 18 = 4x + 30
Subtract 18 from both sides
2x = 4x + 12
Subtract 4x from both sides
-2x = 12
Divide both sides by -2
x = -6
Where she did something different than me is her mistake
Hope this helps!
You might be interested in
2 = coefficient
e = variable
- = operation
f = variable
2e = 2 × e
f subtracted from the product of two and e
The first step would be to isolate a variable (solve for a variable)....so u will have something to sub into the other equation
1 1/16 is the answer!! Hope this helps! <3 x
