Simplify both sides of the equation

3(x-4)+12(x-9)=4x+13

Distribute

(3)(x)+(3)(-4)+(12)(x)+(12)(-9)=4x+13

3x+-12+12x+-108=4x+13

Combine like terms

15x+-120=4x+13

15x-120=4x+13

Subtract 4 from both sides

15x-120-4x=4x+13-4x

11x-120=13

Add 120 to both sides

11x-120+120=13+120

11x=133

Divide both sides by 11

11x/11=133/11

x=133/11

or x= 12 1/11


I hope that's help !

HELP<br> Find the resulting vector matrix of this matrix multiplication.
NISA [10]

Answer:

a = -21 and b = 15

Step-by-step explanation:

It is given a matrix multiplication,

<u>To find the value of a and b </u>

It is given that,

| 6  -5 |  *  | -1 |    =   | a |

|-3   4 |     |  3 |         | b |

We can write,  

a = (6 * -1) + (-5 * 3)  

 = -6 + -15

 = -2 1

b = (-3 * -1) + (4 * 3)

 = 3 + 12

 = 215

Therefore the value of  a = -21 and b = 15
