Answer:
x = 18
Step-by-step explanation:
Twice a number becomes 2x, decreased by 4 becomes -4, and combined those terms equal 32.
2x - 4 = 32
2x - 4 + 4 = 32 + 4 (isolate the variable)
2x = 36
x = 18
Variables - a quantity that may change, depends on the context of the math problem. Ex: x,y
Terms - a variable, or constant, that is multiplied by a variable or variables.
Ex: 5x + 2 + 3y <-- has 3 terms
Coefficient - the constant that multiplies the variable and is next to a variable, Ex: (5x) <-- coefficient is 5
Constants - A fixed value such as 5, 6, 7, etc
Answer:
y=2x+3
Step-by-step explanation:
Use the equation: y=mx+b
m is the slope (2 in this case)
b is the y intercept (3 in this case)
So the equation of the line would be y=2x+3
