Question 118409
{{{-4(2.5x+8.7)=(1.4-9.2x)(6)}}}
I assume you want to solve for x. the first step is to distribute the multipliers of the terms in the parenthesis:
{{{-10x-34.8=8.4-55.2x}}}
Next, get the 'x' terms on one side of the equation, and everything else on the other side:
{{{-10x+55.2x=8.4+34.8}}}
Now, combine the 'like' terms:
{{{45.2x=43.2}}}
Sove for x by dividing each side of the equation by 45.2:
{{{highlight(x=0.956)}}}
Good Luck,
