Question

What is 4(2×-7)+3(3×-1)=3(2-×)​

Answer 1

x =
`(71)/(3)`

Explanation:

1. Simplify/distribute each side.

`4(2)(-7)+3(3)(-1)=3(2-x)`

`4(2)(-7)+3(3)(-1)=(3)(2)+(3)(-x)`

`-56+-9=6+-3x`

2. Flip the equation around.

`-3x+6=-65`

3. Subtract 6 to balance the equation.

`-3x+6-6=-65-6`

`-3x=-71`

4. Divide each side by 3. We know they are in the same fact family.

`(-3x)/(-3) = (-71)/(3)`

Answer 2

x=37/20

Explanation:

4(2x-7)+3(3x-1)=3(2-x)

8x-28+9x-3=6-3x

17x+3x=6+31

20x=37
