Question

Solve the following: a) 4x-1 / 2= x+7 b) 3x + 2 = 2x + 13 /3

Answer 1

Answer:

a) 2.5

b)2.33

Step-by-step explanation:

a)

$4x-\frac{1}{2}= x+7$

Bring the numerals to the right hand side and the x terms to the left hand side

$4x-x=7+\frac{1}{2}$

Simplify

$3x=\frac{15}{2}$

Divide 3 on both sides, to get x

$x=\frac{5}{2} =2.5$

b)

$3x+2=2x+\frac{13}{3}$

Bring the numerals to the right hand side and the x terms to the left hand side

$3x-2x=\frac{13}{3}-2$

Simplify

$x=\frac{7}{3} =2.33$
