so each equation part eh x plus 4.2 equals negative 18.9. To isolate the variable, undo the addition using subtraction. Subtract 4.2 from each side of the equation. X is equal to negative. 18.9 minus 4.2 x equals negative 23.1 part B X minus 4.2 equals negative 18.9. To isolate the variable undo subtraction using edition, add 4.2 to both sides of the equation. X equals negative. 18.9 plus 4.2 x equals negative 14.7 Part See 4.2 x is equal to negative 18.9. To isolate the variable, undo the product using division. Divide both sides by 4.2 x equals negative. 18.9 divided by 4.2 x equals negative 4.5 Part D X, divided by 4.2, is equal to negative 18.9. To isolate the variable, multiply both sides by 4.2 x equals negative 18.9 times 4.2 x equals negative. 79.38
