Question

1. Solve z
a) 3 (x + 4) + 2 (4x + 7) = 2 x + 29
b) 2y - 1 = 7​

Answer 1

Answer:

a) x=1/3

b) y=3

Step-by-step explanation:

a) 3x+12+8x+14=2x+29

11x-2x=29-26

9x=3

x=1/3

b) 2y=7-1

y=6/2

y=3

Answer 2

Answer:

a) x = $\sf{\dfrac{1}{3}}$

b) y=4

Step-by-step explanation:

Given :

a) 3(x+4)+2(4x+7)=2x+29

b) 2y-1=7

To find :

a) The value of x

b) The value of y

Solution :

a) -:

$:\implies\sf{3(x+4)+2(4x+7)=2x+29}$

$:\implies\sf{3x+12+8x+14=2x+29}$

$:\implies\sf{3x+8x+12+14=2x+29}$

$:\implies\sf{11x+26=2x+29}$

$:\implies\sf{11x-2x=29-26}$

$:\implies\sf{9x=3}$

$:\implies\sf{x=\dfrac{3}{9}}$

$:\implies\sf{x=\dfrac{1}{3}}$

The value of x is $\sf{\dfrac{1}{3}}$....

b) -:

$:\implies\sf{2y-1=7}$

$:\implies\sf{2y=7+1}$

$:\implies\sf{2y=8}$

$:\implies\sf{y=\dfrac{8}{2}}$

$:\implies\sf{y=4}$

So , the value of y is 4 ....
