Question 177337
equation is:
{{{3*(x-0.87)-2*x = 4.98}}}
remove the parentheses:
{{{3*x - 3*.87 - 2*x = 4.98}}}
combine like terms:
{{{x - 3*.87 = 4.98}}}
add 3*.87 to both sides of the equation to get:
{{{x = 4.98 + 3*.87}}}
simplify:
{{{x = 4.98 + 2.61}}}
combine like terms:
{{{x = 7.59}}}
that should be your answer.
to verify that it's right, substitute in your original equation.
{{{3*(x-0.87)-2*x = 4.98}}}
becomes:
{{{3*(7.59 -0.87)-2*7.59 = 4.98}}}
which becomes:
{{{3*6.72 - 2*7.59 = 4.98}}}
which becomes:
{{{20.16 - 15.18 = 4.98}}}
which becomes:
4.98 = 4.98
equation is true.
value of 7.59 for x is good.
your answer is:
x = 7.59
