Answer:

x = -6

y = -5

Step-by-step explanation:

5x - 4(-5) = -10

5x + 20 = -10

5x = -10 - 20

A 236 inch board is cut into two pieces. one piece is three times the length of the other. find the length of the two pieces
kirill [66]

let length of one piece = x

length of other piece = 236-x

one piece is three times the length of the other

x=3(236-x)

x=708-3x

4x=708

x=177

so first piece is 177 inches long and second piece is (236-177)= 59 inches long
