You can put this solution on YOUR website!
solve : -10.8x + 1.4 = -47.6 - 1.0x
:
Make this simple, multiply eq by -10 and you have:
108x - 14 = 476 + 10x
;
subtract 10x from both sides
add 14 to both sides, results
108x - 10x = 476 + 14
98x = 490
divide both sides by 98
x = 490%2F98
x = 5

:
Check using x=5 in the original equation
-10.8(5) + 1.4 = -47.6 - 1.0(5)
-54 + 1.4 = -47.6 - 5
-52.6 = -52.6, equality reigns, a good solution
