Answer: x=4

given equation: 8 - 2x= 5(x-4)

STEP 1: distribute the 5 with ONLY the parenthesis which is (x-4)

so it will be 5x-20 (-20 because 5 x -4= -20)

Now the equation is 8 - 2x= 5x - 20

STEP 2: ADD 20 on both SIDES

8+20= 28

New equation: 28 - 2x= 5x

STEP 3: ADD 2x on both sides 2x+5x= 7x

STEP 4: Now divide 28 by 7

28/7= 4

Therefor x= 4

X=3m/2-m <br><br>make m the subject of the formula<br>help me plss
wel

Answer:

2X/(3+X)

Step-by-step explanation:

X = 3m/2-m

Cross multiply both sides

X × (2-m)= 3m

2X-Xm= 3m

2X= 3m+Xm

2X= m(3+X)

Divide both sides by the coefficient of m which is (3+X)

m= 2X/(3+X)
