lol i forgot how to do this can someone answer please!?!!
okay, 4(x-7)= 2
first, distribute.
(4*x)(4*-7)=2
then do the multiplication.
4x-28=2
then add.
4x-28(+28)=2(+28)
combine the terms.
4x=30
divide.
4x( /4)= 30 (/4)
done!
X = 7.5
:].
implifying
4(x + -7) = 2
Reorder the terms:
4(-7 + x) = 2
(-7 * 4 + x * 4) = 2
(-28 + 4x) = 2
Solving
-28 + 4x = 2
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '28' to each side of the equation.
-28 + 28 + 4x = 2 + 28
Combine like terms: -28 + 28 = 0
0 + 4x = 2 + 28
4x = 2 + 28
Combine like terms: 2 + 28 = 30
4x = 30
Divide each side by '4'.
x = 7.5
Simplifying
4(x - 7) = 2
4x - 28 = 2
x = 7.5 or 7 1/2.
4(x-7)=2
x = 15/2
distributive property:
x=7.5
