Question

Solve the following equations and verify the following7x+5=3(x-2)-1

Answer 1

Answer:7X2+5=3X-6-1

7X2-3X2=-5-6-1

4X=-12 then x=-3

Answer 2

${\bold{\huge{\textbf{\red{Answer}}}}}$

${\bold{\large{\textbf{Given\: equation:}}}}$

${\bold{\purple{7x+ 5 = 3(x-2)-1}}}$

open braket:

$\bold{7x+5=3x-6-1}$

saprate the varibles and constants

$\bold{7x-3x= -7-5}$

$\bold{4x= - 12}$

$\bold{x= \frac{-12}{4}}$

${\bold{\red{\boxed{x=-3}}}}$

${\bold{\large{\textbf{To\: verify:}}}}$

put the value of x in the given equation:

$\bold{7×(-3)+5= 3((-3)-2)-1}$

$\bold{-21+5=-15-1 }$

$\bold{-16 = -16}$
