Multiply top equation by -2, then add equations so b drops out....solve for a...plug in a to get b
I don’t even know the answer to be honest
Let t = the temperature
stays above → > also above tells you it is not equal to the given number
Answer t > -15
the solution to the system of equation from the replacement set is -5
Given the equation −6z+1=−4−7z, we are to find the value of z from the given equation:
Given
−6z+1=−4−7z
Collect the like terms;
-6z + 7z = -4 - 1
Simplify the result
z = -4 -1
z= -5
Hence the solution to the system of the equation from the replacement set is -5
