Question

How do i solve 6(3+x)=23

Answer 1

x=5/6

Step-by-step explanation:

Start by factoring in 6, which will make the equation look like this: 18+6x=23

The parenthesis can be removed because they're no longer needed. The next step is to subtract 18 from 23, giving you 6x=5. Then you want to divide 5 by 6 to isolate x, which will give you x=5/6. Hope this helps.

Answer 2

y=-2x+6 ........(1)

3y-x+3=23.........(2)

Substitute y = -2x+6 into (2) and solve for x :

3( -2x+6) - x +3 = 23

- 6x +18 - x +3 =23

- 7x = 2

x =- 2/7

Substitute : x into (1) : y = -2 (-2/7)+6 = 46/7
