2 answers:
Solving two-variable linear equations
5p + 9c = p is:
Sentences that have the same relationship are called equations
Linear equations are open sentences that have the same relationship with a variable and one rank
One variable linear equation is an equation that has a variable and the exponent number is one. Can be stated in the form:
ax = b or ax + b = c, where
a, b, and c are constants, x is a variable
Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one
Can be stated in the form:
ax + by = c
x, y = variable
The solution of linear equations can be done by:
- 1. substitution, elimination
- 2. increase or decrease both segments with the same number
- 3. multiplying or dividing two segments with equal numbers
- 4. graph
In the task, it's known linear equations :
5p + 9c = p
We will solve it using methods 2 and 3
- 1. methods 2
we reduce the two segments by 5p, so expect the left side to have 1 variable
5p + 9c -5p = p -5p
9c = -4p
- 2. methods 3
dividing the two segments by the number 9, so it is expected that the left side has the value c
the slope-intercept form of the linear equation
