Question

-5(-3x+1)= 45 solve for x
​

Answer 1

x=
`(10)/(3)`

Explanation:

Hi there!

We are given the equation -5(-3x+1)=45 and we need to solve for x

we do this by isolating x by itself on one side of the equation; the numbers (the value of x) is on the other side

First, do the distributive property and distribute -5 on -3x and 1 on the left side (multiply both -3x and 1 by -5)

15x-5=45

add 5 to both sides (-5+5=0)

15-5=45

+5 +5

_________

15x=50

divide both sides by 15 (15÷15=1)

15x=50

÷15 ÷15

________

x=
`(50)/(15)`

we can simplify this fraction by factoring five out of 50 and 15

x=
`(10*5)/(3*5)`

cancel 5 out of the numerator and denominator

x=
`(10)/(3)`

The answer can be left as an improper fraction

Hope this helps! :)
