x=4/7

Explanation:

get x alone.

1st get 3 on the other side of the = sign by using the opposite sign. the opposite of addition is subtraction

-5x+3=2x-1

-3 -3

-5x=2x-1-3

-5x=2x-4

now we get the xs together. the opposite of addition( the 2 is positive) is subtraction

-5x=2x-4

-2x -2x

-7x=-4

now let's get the -7 out of here. -7 is multiplying by x. the opposite of multiplication is division.

-7x = -4

-7. -7

x=-4/-7

negative divided by a negative is a positive

x=4/7
