Question

Help please! Solve the proportion for x.

Answer 1

1+3x /4= 5/2
1+3x = 5*4/2
1+3x =10
3x =9
x = 3

Answer 2

Make the denominators all the same.

LCM (4;2) = 4

$\frac{1+3x}{4} = \frac{10}{4}$

Multiply both fractions for 4 to delete denominators

1+3x = 10

Move know terms to the right with changed sign

3x = 10-1

3x = 9

Since the x is multiplied for 3, divide both terms for 3

3x/3 = 9/3

x = 3
