Question

511 = -7 (10x – 13)
steps

Answer 1

Answer:
`x=-6`

Simplify both sides of the equation

`511=(-7)(10x)+(-7)(-13)(Distribute)\\511=-70x+91`

Flip the equation

`-70x+91=511`

Subtract 91 from both sides

`-70x+91-91=511-91\\-70x=420`

Divide both sides by -70

`-70x/70=420/-70\\x=-6`

Answer 2

`511 = - 7(10x - 13) \\ 511 = - 70x + 91 \\ 511 - 91 = - 70x \\ 420 = - 70x \\ (420)/( - 70) = ( - 70x)/( - 70) \\ \\ x = - 6`

hope this helps you...
