The subtraction property of equality: if we subtract one side of the equation then we also must subtract from the other side of the equation.
The division property of equality: if we divide one side of the equation by a number then we also must divide the other side by the same number.
For this equation:
3 x + 5 = 26
3 x + 5 - 5 = 26 - 5 ( the Subtraction Property of Equality )
3 x = 21
3 x : 3 = 21 : 3 ( the Division Property of Equality )
x = 7
Answer: C ) The standard method for solving an equation like 3 x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.
→Answer:
y = -17
→Step-by-step explanation:
Well first off the f(x) in the equation f(x) = 3x + 7 can also be written as y,
y = 3x + 7
So if x is -8 we need to plug it in for x and solve, simple as that :)
y = 3(-8) + 7
y = -24 +7
y = -17
X+71=108
because they're alternate angles and alternate angles have the same measures
