Question

Which one of the following equations is equivalent to the equation ?
A
6x−22=26x-22=2

Answer 1

We simplify the equation :

2(x+3) + 5x = 34

= 2x + 6 + 5x
= 7x + 6

So, 7x + 6 = 34
x = (34-6)/7 = 4

Equation A : 6x - 22 = 2
x = (22+2)/6 = 4 (so it's equvalent).


Equation B : x/5 = 4
x = 4 x 5 = 20 (not equivalent)

Equation C :
3x - 6 = 12
x = (12+6)/3 = 6 (not equivalent)

Equation D : 6x = 18
x = 18/6 = 3 (not equivalent)

So, it's equation A
