How can you tell that a system of linear equations will have infinitely many solutions without computation?
Contact [7]

If you can manipulate the two equations so that they have exactly the same coefficients (e. g., 3x + 4y = 8 and 2x + 4y = 8), then you conclude that the two lines coincide (overlap), and that there are thus infinitely many solutions.

Use the order of operations to solve 4[2.5 3(20 7)]
liraira [26]
PEMDAS ( Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

4(2.53(207))

Since there are no equations in the parentheses, or exponents, we skip these, and head straight for multiplication:

4(523.7)

Then, do multiplication again:

2094.8

So that means, 4(2.53(207)) = 2094.8

I assume the brackets mean parentheses, since the absolute value of 523.7 does not mean anything in this equation.
