If 10 men can build a house in 90 days, how many men can build a home in 20 days? a) 18 b) 36 c) 45 d) 180

7x+8y=-18, 4x-9y=-3 solve the system of equations

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Solve the system of equations using the linear combination method. {4x−3y=127x−3y=3 enter your answers in the boxes.
