Question 238074
Steps:
a. we need to find x, so you first move 1 to the right sidde of eqn
b. convert 1 into a fractio that can be combined with the fraction next to it
c. divide b y -7 on both sides of equation to find the value of x
.
Problem:
{{{1-7x=-(5/2)}}}
{{{-7x=-(5/2)-1}}}
Sinced any number divided by itself equals 1, let's go for 2/2...
{{{-7x=-(5/2)-(2/2)}}}
{{{-7x=-(7/2)}}}
{{{x=-(7/2)/-7}}} ...same as multiplying by reciprocal... {{{x=-(7/2)*(-1/7)}}}
-7 cancels itself, so you're left with:
{{{x=1/2}}}
