Solve the equation and find what X is. 9x-7=10

Marysya12 [62]

Answer:

x = 1 8/9 or 17/9

Step-by-step explanation:

Step 1: Add 7 to both sides.

$9x - 7 + 7 = 10 + 7$
$9x = 17$

Step 2: Divide both sides by 9.

$\frac{9x}{9} = \frac{17}{9}$
$x = \frac{17}{9} = 1 \frac{8}{9}$

Solve the system of equations -5x – 2y = 13 and 3x-y = 12 by combining the equations

Ne4ueva [31]

Answer:

x=1 y =15

Step-by-step explanation:

hopefully correct

-5x-2y=13 (i)

3x-y=12

-y=12-3x

y=-12+3x (ii)

substitute ii into i

-5x-2(-12+3x)=13

-5x +24-6x=13

-11x=-11

x=1

substitute x into ii

y=-12+3(1)

y=15

. . x=1 and y =15

Y=6x+20 substitution

Oksana_A [137]

Answer:

-10/3 or -3.33

Step-by-step explanation:

substitute 0 for y

0 = 6x + 20

-20 = 6x + 20 - 20 subtract 20 on both sides

-20 = 6x divide by 6 on each side

-20/6 = 6x/6

x = -20/6 simplify

x = -10/3
