Question

Solve the following:
a) 4x - 3 = 2x + 7
b) 2x + 6 = 7x - 14

Answer 1

Answer:

a) 4x-3=2x+7

or, 4x-2x=7+3

or, 2x=10

or, x=10/2

therefore, x=5

b) 2x+6=7x-14

or,2x-7x=-14-6

or, -5x= -20

or, x=20/5

therefore, x=4

Answer 2

GIVEN :-

a) 4x - 3 = 2x + 7

b) 2x + 6 = 7x - 14

TO FIND :-

x value

PROOF :-

$a] \\4x-3=2x+7\\\\4x-2x=7+3\\\\ 2x=10\\\\ x= \frac{10}{2} \\\\ x=5$

$b] \\2x+6=7x-14\\\\2x-7x=-14-6\\\\-5x= -20\\\\x= \frac{20}{5} \\\\ x=4$

hope that helps u :-)
