Answer: Linear equations in two variables. If a, b, and r are real numbers (and if a and b are not both equal to 0) then ax+by = r is called a linear equation in two variables. (The “two variables” are the x and the y.) The numbers a and b are called the coefficients of the equation ax+by = r.
Step-by-step explanation:
Answer:x=-3
Step-by-step explanation:
2x-1=-7
Add 1 to each side
2x=-6
Divide each side by 2
x=-3
Factor the expression and your answer would be
- (5xy + 16x - 26y)

Step-by-step explanation:
300/60%=180
Answer:
-1/2 > x > -3
Step-by-step explanation:
i)
-2x+3>4
-2x> 1
x < -1/2
ii)
-2x+3<9
-2x<6
x > -3
= -1/2 > x > -3
