What is consistent Equation?
A linear or nonlinear system of equations is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity.
Let x represents the number of one-bedroom houses and y represents the number of two bedroom houses.
According to Question,
Total number of houses is 12 i.e. x + y = 12..........(i)
Total we have 88 windows in which 6 windows can be use in one bedroom house and 9 windows can be used in two bedroom house so,
6x + 9y = 88 ..................(ii)
From Equation (i) and (ii), we get
x = 7 and y = 5
Thus, Builder can build 7 one bedroom houses and 5 two bedroom houses.

Answer:
Step-by-step explanation:
4.5 miles
Total distance between the trains = 348 miles
Total time to cross that distance by trains = 3 h.
So, sum of their speed would be: 348/3 = 116
A.T.Q,
Speed of train 1 - speed of train 2 = 22
so, two equation that has formed are:
a+b=116
a-b=22, a=b+22
Substitute that in above equation; b+22+b=116
2b= 94, b=47 & a=116-47 =69
Speed of the TRAIN IS 47 & 69 miles per hour.
