Anumber is increased by 3.5 and a result is -4.3 find the number -7.8 -7.4 -7.1 -1.2

let "a number" = "x"

note that increased = +

x + 3.5 = -4.3

solve for x. note the equal sign. what you do to one side, you do to the other. subtract 3.5 from both sides

x + 3.5 (-3.5) = -4.3 (-3.5)

x = -4.3 - 3.5

x = -7.8

-7.8 is your answer for x

3.5 + -7.4 = -3.9

3.5 + -7.1 = -3.6

3.5 + -1.2 = 2.3
