Step-by-step explanation:
all you need to do for the first one is add the P and the M together and the - one M then for the second one you just need to multiply 21 and 27 by 3
Step-by-step explanation:
I think the first equation is the correct answer
After calculating he can buy 11 laptops and 19 tablets
Answer:
x = 41
y = 24
Step-by-step explanation:
Systems of equations is,
-2x - 7y = -250 ------(1)
4x - y = 140 ------(2)
Equation (1) multiplied by 2 then added to equation (2)
-4x -14y = -500
(+) 4x - y = 140
-15y = -360
y =
y = 24
by putting y = 24 in equation (2),
4x - 24 = 140
4x = 140 + 24
x =
x = 41
For x = 41 and y = 24 both the equations are true.
Equation (1), -2(41) - 7(24) = -250 [True]
Equation (2), 4(41) - (24) = 140 [True]
