How do you solve 0.4x-3 equals 1.4? - Answers

Two ways. You can use a calculator, and............ 0.4X - 3 = 1.4 add 3 to each side 0.4X - 3 + 3 = 1.4 + 3 0.4X = 4.4 divide each side by 0.4 (0.4/0.4)X = 4.4/0.4 X = 11 ---------------check 0.4(11) - 3 = 1.4 4.4 - 3 = 1.4 1.4 = 1.4 -------------------------checks Or, without a calculator; use fractions ( keep as 10ths ) 4/10X - 30/10 = 1 and 4/10 ( which is 14/10 ) 4/10X - 30/10 = 14/10 add 30/10 to both sides 4/10X = 44/10 now, dividing by 4/10 is same as multiplying by 10/4 ( 44/10 *10/4 ) tens cancel. 44/4 is fraction remaining. X = 11 ----------------------same answer ( you try this check )
