(5x)/7 - x/14 = 9/7 solve for the unknown value this is a linear equation

Ahat [919]

Step-by-step explanation:

$\longmapsto \rm \dfrac{5x}{7} - \dfrac{x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{10x + x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{11x}{14} = \dfrac{9}{7} \\$

→ 11x(7) = 14(9)

→ 77x = 126

→ x = 126 ÷ 77

→ x = 1.63

What is 12a equal to if 4a plus 6b = 10 and 2a-4b=12?

hram777 [196]

12a=x
4a+6b=10
2a+3b=5
2a-4b=12
a-2b=6
2a+3b+1=a-2b
a+5b+1=0
a=-1-5b

2(-1-5b)+3b=5
-2-10b+3b=5
-2-7b=5
-7b=7
7b=-7
b=-1

-1-5*-1=a
-1+5=a
4=a

4*12=48
12a=48

Hope this helps :)
